== Overview ==


The APC SurgeArrest Personal PER7T is a consumer surge protector intended to provide surge suppression and power distribution for personal computers, peripherals, modems, printers, and other home or office electronics.
The APC SurgeArrest Personal PER7T was marketed as a consumer surge protector intended for home and small-office use during the personal-computing era. The design combines seven grounded outlets with integrated telephone-line protection, APC's Protection Working and Site Wiring Fault indicators, and a six-foot power cord for flexible installation.


The design incorporates seven grounded outlets together with APC's Protection Working and Site Wiring Fault diagnostic indicators. A rocker power switch is positioned near the cord-entry end of the enclosure, while an attached six-foot power cord provides flexibility in desktop and home-office installations.
Although positioned below the company's SurgeArrest Professional product line, teardown examination revealed that the PER7T shares significant design heritage with contemporary Professional-series products. Both families utilize similar enclosure architecture, identical UL listings, comparable protection ratings, and suppression circuitry developed during the same period.


The documented example is noteworthy because it represents APC's consumer-focused SurgeArrest Personal product line, a family that existed alongside the company's higher-end SurgeArrest Professional series during the late 1990s.
Internal examination further revealed that APC maintained separate electrical designs for the Personal and Professional product lines despite their outward similarities. The documented PER7T utilizes a dedicated telephone-protection board and a unique surge-suppression board design not presently documented in the archive's Professional-series examples.


The artifact is also significant due to its association with APC's later 2013 SurgeArrest recall. Documentation accompanying the archived specimen indicates that it was submitted to APC's recall program in 2021, providing a rare example of a recalled surge protector with documented participation in the replacement process.
The artifact is also historically significant due to its connection with APC's 2013 SurgeArrest recall. The unit remained in service for more than two decades before being submitted through APC's recall program, providing a rare documented example of a recalled surge protector with known recall history.
 
As the first Personal-series artifact documented by the OldSurge Archive, the PER7T expands the archive's APC coverage beyond the Professional-family products that presently dominate the collection.


Together, these characteristics make the PER7T an important reference point for understanding APC's late-1990s consumer surge-protection products and their relationship to the broader SurgeArrest family.


== Historical Context ==
== Historical Context ==


During the 1990s APC marketed multiple SurgeArrest product families aimed at different segments of the surge-protection market. While the SurgeArrest Professional series targeted users seeking premium protection and advanced features, the SurgeArrest Personal series was positioned as a more affordable consumer-oriented alternative intended for home and small-office environments.
During the 1990s APC marketed multiple SurgeArrest product families aimed at different segments of the surge-protection market. The SurgeArrest Professional series targeted business and power users seeking premium protection, while the SurgeArrest Personal series was marketed toward home users and small offices requiring protection for personal computers, peripherals, modems, fax machines, and related electronics.
 
By the late 1990s personal computers, dial-up Internet access, fax machines, and other electronic equipment had become increasingly common in homes and small businesses. Products such as the PER7T reflected growing consumer demand for affordable surge protection capable of safeguarding both power and communication connections.


The PER7T belongs to APC's recall-era SurgeArrest generation manufactured between 1993 and 2002. Products from this period were later included in APC's 2013 SurgeArrest recall after reports of overheating, smoking, melting, and fire-related incidents. The documented example's 1998 manufacturing date places it within the affected production range.
By the late 1990s personal computers, dial-up Internet access, and networked home offices had become increasingly common. Products such as the PER7T addressed the growing need for affordable protection not only for AC power connections, but also for telephone lines used by modems and communications equipment.


Compared with the contemporary APC SurgeArrest Professional PRO7 family documented elsewhere in the archive, the Personal-series design appears intended for a more consumer-oriented market segment. The enclosure utilizes a wider footprint, incorporates dedicated diagnostic indicators, and emphasizes ease of use while retaining APC's established SurgeArrest branding and protection technologies.
The documented example was manufactured in 1998 during the production period later affected by APC's 2013 SurgeArrest recall. As a result, the artifact represents APC's recall-era surge-protection design and provides a useful point of comparison with both earlier and later SurgeArrest products.


The documented specimen therefore occupies an important position within APC's product history, illustrating how the company differentiated consumer and professional surge-protection products during the personal-computing era.
Although marketed as part of the Personal family, the PER7T shares substantial design heritage with contemporary APC SurgeArrest Professional products. The documented examples utilize closely related enclosure architecture, identical UL listings, similar diagnostic indicators, and comparable surge-protection ratings. Internal examination, however, revealed that APC maintained separate suppression-board designs for the two product families despite their outward similarities.


The PER7T demonstrates APC's practice of marketing multiple SurgeArrest product families using substantially similar mechanical platforms. While the Professional and Personal product lines were positioned differently within APC's lineup, the documented examples share closely related enclosure architecture and external control layouts.
The PER7T therefore occupies an important position within APC's product history, illustrating how the company adapted a common surge-protection platform to serve different market segments during the personal-computing era.

The weight places the PER7T between the archive's earliest and latest APC SurgeArrest Professional PRO7 examples. The archive's 1998 PRO7 specimen weighs approximately 1 lb 15.9 oz (903 g), while the 2006 and 2017 PRO7 examples each weigh approximately 1 lb 9.6 oz (726 g).
The weight places the PER7T between the archive's earliest and latest APC SurgeArrest Professional PRO7 examples. The archive's 1998 PRO7 specimen weighs approximately 1 lb 15.9 oz (903 g), while the 2006 and 2017 PRO7 examples each weigh approximately 1 lb 9.6 oz (726 g).


The lower weight relative to the contemporary 1998 PRO7 may reflect differences in telephone-protection circuitry, filtering components, internal bus-bar construction, or overall surge-suppression architecture. Additional comparison will be possible following teardown examination.
Teardown examination revealed that the PER7T utilizes a dedicated AC surge-suppression board, a separate telephone-line protection board, a full-length brass outlet-contact assembly, and integrated diagnostic-indicator circuitry. Despite these features, the unit remains approximately 146 g lighter than the archive's 1998 PRO7 specimen.


Despite incorporating seven grounded outlets, telephone-line protection, diagnostic indicators, and a six-foot power cord, the PER7T remains noticeably lighter than APC's professional-oriented PRO7 product of the same period.
The difference appears attributable to APC's use of a smaller suppression-board design within the Personal series. Although the PER7T shares enclosure architecture, certifications, and protection ratings with the contemporary PRO7, internal examination confirmed that the two product families utilize different suppression-board generations and component layouts.

The APC SurgeArrest Personal PER7T utilizes a beige molded-plastic enclosure measuring approximately 10.25 inches (26.0 cm) long, 4.25 inches (10.8 cm) wide, and 1.75 inches (4.4 cm) tall.


The upper surface incorporates seven grounded receptacles arranged in a single row together with APC's "Protection Working" and "Site Wiring Fault" indicators. A black rocker power switch is positioned near the cord-entry end of the enclosure.
The upper surface incorporates seven grounded receptacles arranged in a single row together with APC's Protection Working and Site Wiring Fault indicators. A black rocker switch is positioned near the cord-entry end of the enclosure, while telephone-line protection is provided through modular IN and OUT connectors located at one end of the housing.


Unlike the APC SurgeArrest Professional PRO7 family, the Personal-series enclosure utilizes a broader footprint and a flatter overall profile.
Examination of the telephone-protection connectors and associated circuitry indicates that only the center conductor pair is protected. The design therefore appears intended for a single analog telephone line rather than multi-line service.


The documented example incorporates a six-foot power cord manufactured by HRSA and the underside incorporates two keyhole-style mounting slots intended for wall or furniture mounting.
The enclosure architecture closely resembles that of contemporary APC SurgeArrest Professional products documented elsewhere in the archive. Overall dimensions, outlet layout, indicator placement, wall-mounting provisions, and general mechanical construction are substantially similar despite the different product-family branding and internal circuitry.


The enclosure closely resembles the APC SurgeArrest Professional PRO7 family documented elsewhere within the archive. Overall dimensions, indicator placement, outlet arrangement, and general enclosure architecture appear substantially similar despite the different product-family branding.
The underside incorporates molded electrical and regulatory information, a serial-number label, two keyhole-style mounting slots, and a holographic UL certification label. Unlike many later APC products documented by the archive, most electrical ratings and certification information are molded directly into the enclosure rather than applied using adhesive labels.


Telephone-line protection is provided through modular input and output jacks located at one end of the enclosure. Examination of the connectors indicates that only the center pair of contacts is populated, suggesting support for a single analog telephone line rather than multi-line service.
The retained UL hologram identifies the device as a listed UL 1363 Power Tap and UL 1449 TVSS. A molded marking reading "R9802" is also present on the enclosure. The significance of this marking has not been determined and may represent a tooling identifier, mold revision, or manufacturing code.


A molded marking reading "R9802" is present on the underside of the enclosure. The significance of this marking has not yet been determined and may represent a tooling identifier, mold revision, or manufacturing code.
The documented example utilizes a molded straight-blade NEMA 5-15P attachment plug connected to an approximately six-foot HRSA-manufactured SJT 14/3 power cord. This differs from the archive's contemporary 1998 APC SurgeArrest Professional PRO7 specimen, which utilizes a right-angle attachment plug and a Bon-Eagle-manufactured power cord.


The underside closely resembles contemporary APC SurgeArrest Professional products. Features include molded regulatory information, a serial-number label, two keyhole-style wall-mounting slots, and a UL hologram certification label.
Moderate wear is visible on the grounding pin of the attachment plug, consistent with repeated insertion and removal during service life. Several deep scratches are also present on the underside of the enclosure, particularly near the recessed serial-number area, although the damage appears entirely cosmetic.
 
Unlike later APC SurgeArrest products documented by the archive that utilize large adhesive regulatory labels, the PER7T incorporates most electrical ratings and certification information directly into the enclosure tooling through molded lettering.

== Date Codes ==


Discussion of serial numbers, molded date wheels, labels, component date codes, manufacturing evidence, and production chronology.
The documented specimen is identified by serial number '''Z98010214399'''. According to APC recall documentation, the third and fourth characters of the serial number indicate the year of manufacture, identifying the unit as a 1998 production example.
 
Disassembly revealed no molded date-code wheels in either enclosure half. This differs from later APC SurgeArrest products documented by the archive, including the 1999 PRO7, which incorporate molded date-code indicators within the enclosure for manufacturing traceability.
 
The absence of molded date-code features suggests that APC introduced this manufacturing-control practice sometime after production of the documented PER7T specimen. As a result, the serial number provides the primary evidence used to establish the manufacturing date of this artifact.

Removal of the upper housing revealed a design considerably more sophisticated than many contemporary consumer surge protectors. The PER7T combines a dedicated AC surge-suppression board, an independent telephone-line protection board, a full-length brass outlet-contact assembly, integrated diagnostic indicators, and a resettable circuit-breaker and rocker-switch assembly.


Electrical distribution is accomplished through a substantial brass outlet-contact assembly extending the length of the enclosure and serving all seven receptacles. Separate circuit boards are mounted within the enclosure to provide AC surge suppression and telephone-line protection functions.
Electrical distribution is accomplished through substantial stamped-brass contact assemblies extending the length of the enclosure and serving all seven receptacles. Internal wiring is neatly routed and incorporates dedicated grounding conductors, mechanical strain relief, and molded supports throughout the enclosure.


Unlike the archive's recently documented COXOC CO-001S, which relies upon a single MOV connected directly across the incoming AC supply, the PER7T utilizes a dedicated suppression assembly and significantly greater component density.
The upper housing incorporates molded outlet barriers, receptacle-positioning features, structural reinforcement ribs, and mounting provisions for the internal outlet-contact assembly. Overall construction quality is consistent with other APC surge-protection products documented by the archive.


The documented example utilizes an HRSA-manufactured SJT 14/3 power cord carrying UL file number E69167 and CSA file number LL52902. Internal wiring appears orderly and utilizes dedicated grounding conductors together with mechanical strain relief at the cord-entry point.
Inspection identified the main surge-suppression circuit board as:
 
The upper housing incorporates molded outlet barriers, receptacle-positioning features, structural reinforcement ribs, and mounting provisions for the internal outlet-contact assembly.
 
Construction quality appears comparable to contemporaneous APC SurgeArrest Professional products documented by the archive, suggesting that both product families shared common mechanical-design philosophies despite differing electronic implementations.
 
Further examination of the suppression and telephone-protection assemblies identified additional component markings and circuit-board revisions discussed below.
 
Unlike later APC PRO7 examples documented by the archive, the PER7T enclosure does not incorporate molded date-code wheels in either enclosure half.
 
No date wheels were observed on the upper or lower housing during disassembly. Consequently, the serial number presently provides the primary basis for manufacturing-date identification.
 
The absence of molded date wheels suggests that APC had not yet adopted the manufacturing-traceability methods seen on later documented PRO7 specimens.
 
Inspection of the underside of the main circuit board identified APC part number:


<pre>
<pre>
AMERICAN POWER CONVERSION
640-0323C
640-0323C
REV 6
REV 6
© 1996
</pre>
</pre>


The board designation differs from the 640-0321-series suppression boards documented in the archive's APC SurgeArrest Professional PRO7 family, indicating that the Personal-series models utilized a distinct circuit-board design despite sharing much of the same enclosure architecture.
Although the board carries the same 1996 copyright year found on the archive's 1998 APC SurgeArrest Professional PRO7 specimen, it represents a different board family. The documented PRO7 utilizes suppression board 640-0321C REV 7, while the PER7T utilizes 640-0323C REV 6.


The main surge-suppression board appears physically smaller and less complex than the suppression assemblies documented in contemporary APC SurgeArrest Professional products. Further examination of the component side will be required to determine whether this reflects reduced filtering, fewer suppression components, or other design differences between the Personal and Professional product families.
The suppression circuitry incorporates multiple surge-protection and filtering components, including at least two metal-oxide varistors (MOVs), resistors, capacitors, diagnostic-indicator circuitry, and protective components associated with the Site Wiring Fault and Protection Working indicators.


The PER7T incorporates a dedicated telephone-line protection circuit board positioned separately from the main surge-suppression assembly.
A primary surge-suppression device is identified as:


The board connects the incoming and outgoing modular telephone connectors through a protection network consisting of fuses, diodes, resistors, and surge-suppression components.
<pre>
ZNR
V20201U
</pre>


Inspection confirmed that only the center pair of contacts is connected through the protection circuitry. The remaining conductor positions within the modular connectors are not populated, indicating that the design was intended to protect a single analog telephone line.
The suppression board is physically smaller than the assembly documented in the archive's contemporary 1998 PRO7 specimen but remains substantially more sophisticated than the minimalist surge-suppression designs found in some consumer products of the period.


Board markings identified the telephone-protection assembly as:
Telephone-line protection is provided by a separate circuit board mounted adjacent to the modular connector assembly. The board carries the marking:


<pre>
<pre>
Line 262: Line 243:
</pre>
</pre>


Additional component-level examination may provide further insight into APC's telephone-protection design practices during the late 1990s.
The assembly incorporates fuses, diodes, resistors, surge-suppression components, and modular input/output connectors. Examination confirmed that only the center conductor pair is routed through the protection circuitry, indicating protection for a single analog telephone line. The remaining connector positions are not populated.


The telephone-protection assembly carries the marking "014060", potentially identifying the PCB design revision or internal APC part number.
Disassembly revealed no molded date-code wheels in either enclosure half. This differs from later APC SurgeArrest products documented by the archive, including the archive's 1999 PRO7 specimen, which incorporates molded date-code indicators for manufacturing traceability. The absence of these features suggests that APC introduced this practice sometime after production of the documented 1998 PER7T.
 
The teardown demonstrates that the PER7T was not simply a Professional-series surge protector with telephone protection added. Although the Personal and Professional families share enclosure architecture, certifications, and protection ratings, internal examination revealed distinct suppression-board designs tailored to their respective product families.

Compared with the archive's 1998 APC SurgeArrest Professional PRO7 specimen, the PER7T utilizes a nearly identical enclosure architecture while adding integrated telephone-line protection and Personal-series branding.
The documented APC SurgeArrest Personal PER7T shares substantial design heritage with the archive's 1998 APC SurgeArrest Professional PRO7 specimen. Both products were manufactured during 1998, utilize seven-outlet enclosures of nearly identical dimensions, carry UL file number E111219, employ 330-volt TVSS ratings across all protection modes, and incorporate suppression boards carrying 1996 APC copyright markings.
 
The documented PRO7 utilizes a Bon-Eagle-manufactured power cord, whereas the documented PER7T utilizes an HRSA-manufactured cord assembly. This difference indicates that APC sourced cord assemblies from multiple suppliers during the same general production period.
 
Further comparison of the internal construction may reveal whether the Personal and Professional product families shared suppression circuitry or diverged internally despite their similar external appearance.
 
The documented PER7T carries UL file number E111219, identical to contemporary APC SurgeArrest Professional PRO7 examples preserved by the archive. This suggests that both product families were evaluated under the same APC UL listing despite differing model designations and feature sets.
 
The documented PER7T carries TVSS suppression ratings of 330 volts for line-to-neutral, line-to-ground, and neutral-to-ground protection paths. These ratings match those documented on the archive's 1998 APC SurgeArrest Professional PRO7 specimen.
 
Regulatory and electrical information is molded directly into the enclosure rather than applied using adhesive labels. This approach permanently preserves rating and certification information and mirrors the construction methods observed on other APC products from the recall-era production period.
 
Later APC SurgeArrest products documented by the archive increasingly relied upon adhesive labels for regulatory and rating information.
 
The documented PER7T shares the same UL file number (E111219), TVSS ratings (330V across all protection modes), general enclosure architecture, wall-mounting provisions, and seven-screw construction observed on the archive's 1998 APC SurgeArrest Professional PRO7 specimen. The similarities suggest that APC's Personal and Professional product families shared significant engineering commonality despite their different market positioning.


The documented PER7T differs from the archive's 1998 APC SurgeArrest Professional PRO7 in several visible respects. While both products share a nearly identical enclosure architecture, the PER7T incorporates telephone-line protection, utilizes an HRSA-manufactured power cord, and employs a straight-blade attachment plug rather than the right-angle plug used on the contemporary PRO7.
Despite these similarities, the two products were not electrically identical. Internal examination revealed that the PER7T utilizes suppression board 640-0323C REV 6, while the contemporary PRO7 utilizes board 640-0321C REV 7. The PER7T also incorporates a dedicated telephone-line protection board that is absent from the documented PRO7 example.


Despite sharing a nearly identical enclosure architecture with the archive's 1998 APC SurgeArrest Professional PRO7 specimen, the PER7T utilizes a different suppression-board family.
Several external differences are also present. The documented PER7T utilizes an HRSA-manufactured six-foot power cord terminated with a straight-blade attachment plug, while the documented PRO7 utilizes a Bon-Eagle-manufactured cord and a right-angle attachment plug. The PER7T additionally provides telephone-line protection through integrated modular connectors and carries SurgeArrest Personal branding rather than SurgeArrest Professional branding.


The documented PRO7 incorporates suppression board 640-0321C REV 7, while the PER7T utilizes board 640-0323C REV 6. The differing board numbers suggest that APC developed separate electrical designs for its Professional and Personal product lines despite substantial external similarities.
The PER7T weighs approximately 757 g, compared with 903 g for the archive's 1998 PRO7 specimen. Teardown examination suggests that the lower weight is primarily attributable to APC's use of a smaller suppression-board assembly despite retaining similar enclosure architecture and protection ratings.


Unlike the archive's contemporaneous PRO7 specimen, the PER7T incorporates a separate telephone-protection subsystem consisting of an independent circuit board and dedicated protection components. The additional circuitry reflects the model's intended role as a combined AC and telephone-line surge protector.
Together, the two products illustrate APC's practice of adapting a common mechanical platform to serve different segments of the surge-protection market. While the Personal and Professional families shared substantial mechanical and regulatory commonality, APC maintained distinct electrical designs and feature sets for each product line.

The APC SurgeArrest Personal PER7T is a seven-outlet surge protector manufactured by APC (American Power Conversion) in 1998 as part of the company's consumer-oriented SurgeArrest Personal product family.

Designed to protect personal computers, peripherals, modems, and other household electronics, the PER7T combines AC surge suppression, telephone-line protection, site-wiring diagnostics, and seven grounded outlets within a compact desktop enclosure.

The documented example is particularly significant because it was manufactured during the production period later affected by the APC SurgeArrest Recall (2013). This unit was submitted through APC's recall program in 2021, providing an unusual opportunity to examine a recalled surge protector with documented participation in the replacement process.

As the first SurgeArrest Personal product preserved by the OldSurge Archive, the PER7T expands documentation beyond APC's better-known SurgeArrest Professional family and helps illustrate how APC differentiated consumer and professional surge-protection products during the late 1990s.

Overview

The APC SurgeArrest Personal PER7T was marketed as a consumer surge protector intended for home and small-office use during the personal-computing era. The design combines seven grounded outlets with integrated telephone-line protection, APC's Protection Working and Site Wiring Fault indicators, and a six-foot power cord for flexible installation.

Although positioned below the company's SurgeArrest Professional product line, teardown examination revealed that the PER7T shares significant design heritage with contemporary Professional-series products. Both families utilize similar enclosure architecture, identical UL listings, comparable protection ratings, and suppression circuitry developed during the same period.

Internal examination further revealed that APC maintained separate electrical designs for the Personal and Professional product lines despite their outward similarities. The documented PER7T utilizes a dedicated telephone-protection board and a unique surge-suppression board design not presently documented in the archive's Professional-series examples.

The artifact is also historically significant due to its connection with APC's 2013 SurgeArrest recall. The unit remained in service for more than two decades before being submitted through APC's recall program, providing a rare documented example of a recalled surge protector with known recall history.

Together, these characteristics make the PER7T an important reference point for understanding APC's late-1990s consumer surge-protection products and their relationship to the broader SurgeArrest family.

Historical Context

During the 1990s APC marketed multiple SurgeArrest product families aimed at different segments of the surge-protection market. The SurgeArrest Professional series targeted business and power users seeking premium protection, while the SurgeArrest Personal series was marketed toward home users and small offices requiring protection for personal computers, peripherals, modems, fax machines, and related electronics.

By the late 1990s personal computers, dial-up Internet access, and networked home offices had become increasingly common. Products such as the PER7T addressed the growing need for affordable protection not only for AC power connections, but also for telephone lines used by modems and communications equipment.

The documented example was manufactured in 1998 during the production period later affected by APC's 2013 SurgeArrest recall. As a result, the artifact represents APC's recall-era surge-protection design and provides a useful point of comparison with both earlier and later SurgeArrest products.

Although marketed as part of the Personal family, the PER7T shares substantial design heritage with contemporary APC SurgeArrest Professional products. The documented examples utilize closely related enclosure architecture, identical UL listings, similar diagnostic indicators, and comparable surge-protection ratings. Internal examination, however, revealed that APC maintained separate suppression-board designs for the two product families despite their outward similarities.

The PER7T therefore occupies an important position within APC's product history, illustrating how the company adapted a common surge-protection platform to serve different market segments during the personal-computing era.

Weight

The documented APC SurgeArrest Personal PER7T weighs approximately 1 lb 10.7 oz (757 g).

The weight places the PER7T between the archive's earliest and latest APC SurgeArrest Professional PRO7 examples. The archive's 1998 PRO7 specimen weighs approximately 1 lb 15.9 oz (903 g), while the 2006 and 2017 PRO7 examples each weigh approximately 1 lb 9.6 oz (726 g).

Teardown examination revealed that the PER7T utilizes a dedicated AC surge-suppression board, a separate telephone-line protection board, a full-length brass outlet-contact assembly, and integrated diagnostic-indicator circuitry. Despite these features, the unit remains approximately 146 g lighter than the archive's 1998 PRO7 specimen.

The difference appears attributable to APC's use of a smaller suppression-board design within the Personal series. Although the PER7T shares enclosure architecture, certifications, and protection ratings with the contemporary PRO7, internal examination confirmed that the two product families utilize different suppression-board generations and component layouts.

The resulting design occupies a position between APC's higher-end Professional-series products and the simpler consumer surge protectors documented elsewhere in the archive.

Physical Characteristics

The APC SurgeArrest Personal PER7T utilizes a beige molded-plastic enclosure measuring approximately 10.25 inches (26.0 cm) long, 4.25 inches (10.8 cm) wide, and 1.75 inches (4.4 cm) tall.

The upper surface incorporates seven grounded receptacles arranged in a single row together with APC's Protection Working and Site Wiring Fault indicators. A black rocker switch is positioned near the cord-entry end of the enclosure, while telephone-line protection is provided through modular IN and OUT connectors located at one end of the housing.

Examination of the telephone-protection connectors and associated circuitry indicates that only the center conductor pair is protected. The design therefore appears intended for a single analog telephone line rather than multi-line service.

The enclosure architecture closely resembles that of contemporary APC SurgeArrest Professional products documented elsewhere in the archive. Overall dimensions, outlet layout, indicator placement, wall-mounting provisions, and general mechanical construction are substantially similar despite the different product-family branding and internal circuitry.

The underside incorporates molded electrical and regulatory information, a serial-number label, two keyhole-style mounting slots, and a holographic UL certification label. Unlike many later APC products documented by the archive, most electrical ratings and certification information are molded directly into the enclosure rather than applied using adhesive labels.

The retained UL hologram identifies the device as a listed UL 1363 Power Tap and UL 1449 TVSS. A molded marking reading "R9802" is also present on the enclosure. The significance of this marking has not been determined and may represent a tooling identifier, mold revision, or manufacturing code.

The documented example utilizes a molded straight-blade NEMA 5-15P attachment plug connected to an approximately six-foot HRSA-manufactured SJT 14/3 power cord. This differs from the archive's contemporary 1998 APC SurgeArrest Professional PRO7 specimen, which utilizes a right-angle attachment plug and a Bon-Eagle-manufactured power cord.

Moderate wear is visible on the grounding pin of the attachment plug, consistent with repeated insertion and removal during service life. Several deep scratches are also present on the underside of the enclosure, particularly near the recessed serial-number area, although the damage appears entirely cosmetic.

Date Codes

The documented specimen is identified by serial number Z98010214399. According to APC recall documentation, the third and fourth characters of the serial number indicate the year of manufacture, identifying the unit as a 1998 production example.

Disassembly revealed no molded date-code wheels in either enclosure half. This differs from later APC SurgeArrest products documented by the archive, including the 1999 PRO7, which incorporate molded date-code indicators within the enclosure for manufacturing traceability.

The absence of molded date-code features suggests that APC introduced this manufacturing-control practice sometime after production of the documented PER7T specimen. As a result, the serial number provides the primary evidence used to establish the manufacturing date of this artifact.

Condition Upon Acquisition

The documented example was acquired in used condition and exhibited cosmetic wear consistent with long-term residential or office service.

The enclosure remained structurally intact and displayed moderate surface wear, minor scuffs, and localized discoloration. Several scratches and abrasion marks were present on both the upper and lower enclosure surfaces, including deep scratches on the underside near the recessed serial-number area.

A transfer mark consistent with prolonged contact from an electrical plug or similar object was present on the receptacle face near the third outlet from the left.

The attached power cord, attachment plug, rocker switch, indicator lenses, telephone-protection ports, and receptacles appeared complete and undamaged upon initial examination.

Unlike some recalled APC SurgeArrest products documented by the archive, the specimen exhibited no visible evidence of overheating, melted plastic, plug-body separation, heat discoloration, or electrical damage.

The unit was cleaned prior to detailed photography, testing, and internal examination.

Teardown

The APC SurgeArrest Personal PER7T enclosure is secured using seven Phillips-head screws and can be opened non-destructively.

Removal of the upper housing revealed a design considerably more sophisticated than many contemporary consumer surge protectors. The PER7T combines a dedicated AC surge-suppression board, an independent telephone-line protection board, a full-length brass outlet-contact assembly, integrated diagnostic indicators, and a resettable circuit-breaker and rocker-switch assembly.

Electrical distribution is accomplished through substantial stamped-brass contact assemblies extending the length of the enclosure and serving all seven receptacles. Internal wiring is neatly routed and incorporates dedicated grounding conductors, mechanical strain relief, and molded supports throughout the enclosure.

The upper housing incorporates molded outlet barriers, receptacle-positioning features, structural reinforcement ribs, and mounting provisions for the internal outlet-contact assembly. Overall construction quality is consistent with other APC surge-protection products documented by the archive.

Inspection identified the main surge-suppression circuit board as: 

AMERICAN POWER CONVERSION
640-0323C
REV 6
© 1996

Although the board carries the same 1996 copyright year found on the archive's 1998 APC SurgeArrest Professional PRO7 specimen, it represents a different board family. The documented PRO7 utilizes suppression board 640-0321C REV 7, while the PER7T utilizes 640-0323C REV 6.

The suppression circuitry incorporates multiple surge-protection and filtering components, including at least two metal-oxide varistors (MOVs), resistors, capacitors, diagnostic-indicator circuitry, and protective components associated with the Site Wiring Fault and Protection Working indicators.

A primary surge-suppression device is identified as: 

ZNR
V20201U

The suppression board is physically smaller than the assembly documented in the archive's contemporary 1998 PRO7 specimen but remains substantially more sophisticated than the minimalist surge-suppression designs found in some consumer products of the period.

Telephone-line protection is provided by a separate circuit board mounted adjacent to the modular connector assembly. The board carries the marking: 

014060

The assembly incorporates fuses, diodes, resistors, surge-suppression components, and modular input/output connectors. Examination confirmed that only the center conductor pair is routed through the protection circuitry, indicating protection for a single analog telephone line. The remaining connector positions are not populated.

Disassembly revealed no molded date-code wheels in either enclosure half. This differs from later APC SurgeArrest products documented by the archive, including the archive's 1999 PRO7 specimen, which incorporates molded date-code indicators for manufacturing traceability. The absence of these features suggests that APC introduced this practice sometime after production of the documented 1998 PER7T.

The teardown demonstrates that the PER7T was not simply a Professional-series surge protector with telephone protection added. Although the Personal and Professional families share enclosure architecture, certifications, and protection ratings, internal examination revealed distinct suppression-board designs tailored to their respective product families.

Comparison Notes

The documented APC SurgeArrest Personal PER7T shares substantial design heritage with the archive's 1998 APC SurgeArrest Professional PRO7 specimen. Both products were manufactured during 1998, utilize seven-outlet enclosures of nearly identical dimensions, carry UL file number E111219, employ 330-volt TVSS ratings across all protection modes, and incorporate suppression boards carrying 1996 APC copyright markings.

Despite these similarities, the two products were not electrically identical. Internal examination revealed that the PER7T utilizes suppression board 640-0323C REV 6, while the contemporary PRO7 utilizes board 640-0321C REV 7. The PER7T also incorporates a dedicated telephone-line protection board that is absent from the documented PRO7 example.

Several external differences are also present. The documented PER7T utilizes an HRSA-manufactured six-foot power cord terminated with a straight-blade attachment plug, while the documented PRO7 utilizes a Bon-Eagle-manufactured cord and a right-angle attachment plug. The PER7T additionally provides telephone-line protection through integrated modular connectors and carries SurgeArrest Personal branding rather than SurgeArrest Professional branding.

The PER7T weighs approximately 757 g, compared with 903 g for the archive's 1998 PRO7 specimen. Teardown examination suggests that the lower weight is primarily attributable to APC's use of a smaller suppression-board assembly despite retaining similar enclosure architecture and protection ratings.

Together, the two products illustrate APC's practice of adapting a common mechanical platform to serve different segments of the surge-protection market. While the Personal and Professional families shared substantial mechanical and regulatory commonality, APC maintained distinct electrical designs and feature sets for each product line.

Recall Information

The APC SurgeArrest Personal PER7T was included in APC's 2013 SurgeArrest recall affecting approximately 15 million APC 7-Series and 8-Series surge protectors manufactured between 1993 and 2002.

According to APC and the U.S. Consumer Product Safety Commission (CPSC), affected units could overheat, smoke, melt, and pose a fire hazard. The recall included multiple SurgeArrest product families, including the Personal, Professional, Performance, and Network series.

The documented example carries serial number Z98010214399 and was manufactured in 1998, placing it within the affected recall period.

Documentation accompanying the artifact indicates that the unit was submitted to APC's recall program in June 2021. A replacement APC SurgeArrest surge protector manufactured in 2021 was reportedly received through the recall process and remains preserved alongside the recalled specimen.

As a result, this artifact represents a rare documented example of a recalled APC SurgeArrest product with a known recall-participation history.


Historical References
