APC SurgeArrest Professional PRO7 (Z99080215662)
The APC SurgeArrest Professional PRO7 documented here bears serial number Z99080215662, indicating manufacture in 1999.
The documented example represents an intermediate APC PRO7 revision between the archive's 1998 and 2002 examples. Internal examination identified a suppression board carrying a ©1997 copyright marking, documenting another previously unrecorded revision within the APC PRO7 product family.
This example remains within the production period covered by the APC SurgeArrest Recall (2013).

Weight
The documented example weighs approximately 1 lb 15.8 oz (902 g).
This weight is nearly identical to the 1998 APC PRO7 specimen documented by the OldSurge Archive, which weighed approximately 1 lb 15.9 oz (903 g).
The similarity suggests that APC made relatively few changes to the overall mechanical and electrical construction of the PRO7 between the 1998 and 1999 production periods despite implementing a newer suppression-board revision.
Physical Description
The documented example exhibits moderate cosmetic wear including scratches, scuffs, and abrasions around the APC branding and indicator section.
The overall enclosure design remains substantially similar to the 1998 and 2002 APC PRO7 examples documented by the OldSurge Archive, demonstrating continuity in APC's mechanical design during this period.
The underside incorporates two keyhole-style mounting slots, a recessed serial-number label, molded electrical ratings, safety markings, and certification information.
A molded "9934" marking is present on the underside of the enclosure. The marking likely represents a 1999 week-34 production code corresponding approximately to late August 1999. This interpretation is consistent with the documented serial number and internal molded date-code wheels.
The documented example utilizes an APC-branded right-angle grounded attachment plug connected to an attached six-foot power cord.
The plug design was intended to reduce the distance between the connected equipment and the wall. However, when installed in modern receptacles configured with the grounding contact in the upward position, the cord exits upward before bending downward. As a result, the design does not sit as close to the wall as many contemporary low-profile right-angle plugs.
The attached power cord utilizes SJT-rated three-conductor 16 AWG cable bearing UL file number E160081 and CSA file number LL86908. The cable is marked for 75°C operation under UL standards and 60°C operation under CSA standards and carries VW-1 and FT2 flame ratings. No cord manufacturer has been positively identified, although the cable bears the marking "N.S."

Condition Upon Acquisition
The documented example was acquired as part of a lot containing fifteen APC SurgeArrest Professional surge protectors.
The enclosure exhibited moderate cosmetic wear including scratches, scuffs, abrasions, and localized wear around the APC logo and indicator section. Dust accumulation and cord discoloration consistent with long-term use and storage were also present.
No evidence of melting, cracking, overheating, or major physical damage was observed during external examination.
The unit was cleaned prior to detailed photography and testing.
Testing
The documented example was tested for basic electrical operation and wiring integrity. The rocker switch successfully controlled power to all outlets. When connected to a properly wired receptacle and switched ON, the green Protection Working indicator illuminated normally while the red Site Wiring Fault indicator remained unlit. Testing with a receptacle tester confirmed correct hot, neutral, and ground wiring with no wiring faults detected.

Teardown
The APC SurgeArrest Professional PRO7 is assembled using multiple Phillips-head screws and can be opened non-destructively.
Following removal of the enclosure screws, the upper housing separated cleanly from the lower enclosure without damage.
The upper housing incorporates molded outlet barriers, structural reinforcing ribs, mounting bosses, and support features intended to retain the outlet-contact assemblies and brass bus bars.
Inspection revealed moderate dust accumulation and localized debris within portions of the upper housing, consistent with long-term service and storage.
The overall internal architecture closely resembles the 1998 APC PRO7 specimen documented by the OldSurge Archive, utilizing stamped-brass bus bars, individual outlet-contact assemblies, dedicated grounding conductors, and a centrally mounted suppression circuit board.
Inspection of the suppression circuit board revealed markings:
APC 640-0321D REV 12 © 1997
The documented example therefore incorporates a previously undocumented APC PRO7 suppression-board revision positioned chronologically between the archive's ©1996 and ©2002 board generations.
Inspection of the upper housing identified molded date-code wheels indicating manufacture during August 1999. The molded date code corresponds closely with the serial number, which also identifies the documented example as an August 1999 production unit.
The date-code wheels provide independent physical confirmation of the manufacturing date and represent the earliest documented APC PRO7 example incorporating this feature preserved by the OldSurge Archive.
The suppression circuitry incorporates dual toroidal EMI/RFI filtering inductors, multiple metal-oxide varistors (MOVs), fuse protection, status-indicator circuitry, and an X2-rated interference-suppression capacitor.
The filtering capacitor is marked:
0.47 µF 250V~ 275V~ X2 6/99
The June 1999 component date code is consistent with the documented example's August 1999 manufacturing date and provides additional evidence supporting the production period.
Multiple independent manufacturing-date indicators support the documented August 1999 production date, including the serial number, molded date-code wheels, a UL hologram marked 07/99, and an X2-rated suppression capacitor carrying a 6/99 date code.
No evidence of overheating, burned traces, catastrophic component failure, carbon tracking, significant corrosion, or previous repair activity was observed during internal examination. The documented example remained fully functional during testing.

Comparison Notes
The documented example occupies an intermediate position within the APC PRO7 timeline documented by the OldSurge Archive:
- Z98010201706 (1998, ©1996 PCB)
- Z99080215662 (August 1999, ©1997 PCB)
- 2Z0250P17876 (December 2002, ©2002 PCB)
- 4Z0842P07546 (September 2008, ©2002 PCB)
- 7Z1714L05335 (January 2017, ©2009 PCB)
The 1999 specimen documents a previously unrecorded ©1997 suppression-board revision positioned between the earlier ©1996 and later ©2002 board generations. Despite multiple circuit-board revisions, APC retained a remarkably consistent external enclosure design throughout the documented production life of the PRO7 product family.
