Physical Description
The APC SurgeArrest Professional PRO7 utilizes a two-piece plastic enclosure consisting of a rounded upper housing and a flat outlet section containing seven grounded receptacles arranged in a single row. The enclosure features the distinctive curved profile used on many APC SurgeArrest Professional products of this period.
A rocker-style power switch is located near the cord-entry end of the enclosure. Adjacent to the switch are two status indicators: a green Protection Working indicator that reports the status of the surge-suppression circuitry and a red Site Wiring Fault indicator intended to alert users to certain building-wiring conditions.
The cord-entry end incorporates a resettable push-button circuit breaker and a molded strain relief for the attached power cord.
The underside incorporates two keyhole-style mounting slots. The slot arrangement supports installation in either horizontal or vertical orientations, providing flexibility for wall, desk, cabinet, or under-bench mounting.
The documented example bears serial number 7Z1714L05335. Unlike many consumer surge protectors, APC assigned individual serial numbers to units within the SurgeArrest Professional product family. Based on APC serial-number decoding information published in connection with the APC SurgeArrest recall program, the documented example was manufactured in 2017. The unit was manufactured in the Philippines.
The PRO7 utilizes an approximately six-foot SJT-rated power cord terminated with a right-angle grounded attachment plug. Cord markings identify the cable as a three-conductor 14 AWG cord rated for 300 volts and 60°C operation. Both the attachment plug and power cord carry I-SHENG manufacturing markings together with UL and CSA approval markings.
Unlike many modern low-profile plugs designed to direct the power cord downward, the PRO7's right-angle plug exits toward the grounding-pin side of the attachment plug. When connected to receptacles installed in the grounding-pin-up orientation, the cord initially exits upward before bending downward.
Testing
The documented example was tested for basic electrical operation and wiring integrity.
A receptacle tester indicated correct hot, neutral, and ground wiring throughout the surge protector. No open ground, open neutral, reversed polarity, or other wiring faults were detected.
The rocker switch successfully controlled power to all outlets.
During testing, the green Protection Working indicator illuminated, indicating that the surge-suppression circuitry remained operational.
The red Site Wiring Fault indicator remained unlit when connected to a properly wired receptacle.

Teardown
The PRO7 is assembled using multiple screws and can be opened non-destructively.
During disassembly, the upper and lower housing halves separated tightly. Several internal bus-bar assemblies became partially displaced when the enclosure was opened and required careful repositioning before reassembly.
The upper housing contains molded outlet barriers, structural reinforcement features, and integrated mounting-slot supports. Material markings visible within the enclosure identify the housing as FR-HIPS/PVC construction.
The lower housing contains the outlet-contact assemblies, rocker power switch, wiring, outlet bus bars, and a substantial printed circuit board containing the surge-protection and monitoring circuitry.
Unlike simpler surge protectors that rely primarily on stamped bus bars for power distribution, the PRO7 utilizes a combination of bus bars, outlet-contact assemblies, and printed-circuit-board-based power and protection circuitry.
The outlet assemblies are mounted in a molded carrier system that utilizes stamped brass conductors and spring-contact assemblies.
Further examination of the circuit board revealed multiple metal-oxide varistors (MOVs), an inductor, capacitors, and associated discrete components. The configuration indicates that the PRO7 provides both surge suppression and line-noise filtering.
At least one MOV is marked GNR 20D201K. Multiple MOVs are present within the suppression assembly. Their arrangement appears consistent with the protection modes specified on the product label:
- Line-to-Neutral (L-N)
- Line-to-Ground (L-G)
- Neutral-to-Ground (N-G)
The suppression circuit board bears a 2009 American Power Conversion copyright marking. While the documented example was manufactured in 2017, the marking indicates that the underlying circuit design was developed no later than 2009 and remained in production for several years.
A molded date-code wheel visible within the enclosure appears to indicate manufacture of the housing components in January 2017, consistent with the serial-number-derived manufacturing year.
Inspection of the interior revealed no obvious signs of overheating, melting, electrical failure, or component damage.

Condition Upon Acquisition
The documented example was acquired as part of a lot containing twelve APC SurgeArrest Professional surge protectors.
The unit exhibited light dust accumulation and cosmetic wear consistent with normal use. The surge protector was cleaned prior to detailed documentation and photography.
Collection History
The documented example was acquired by the OldSurge Archive in September 2026 as part of a lot containing twelve APC SurgeArrest Professional surge protectors representing multiple models and production dates.
