APC SurgeArrest Professional PRO7 (Z94030204087)
APC SurgeArrest Professional PRO7 (Z94030204087)
The APC SurgeArrest Professional PRO7 documented here bears serial number Z94030204087, indicating manufacture in 1994. The unit was manufactured in China and represents the earliest APC PRO7 specimen currently documented by the OldSurge Archive.
This example is particularly notable for its early branding variation, a suppression board carrying a ©1993 copyright notice, and its inclusion within the manufacturing period affected by the 2013 APC SurgeArrest recall.

Physical Characteristics
The APC PRO7 utilizes a two-section enclosure consisting of a rectangular lower outlet housing and a distinctive curved upper enclosure containing the switch, indicators, and surge-suppression circuitry.
The documented example retains the early Professional SurgeArrest logo design consisting of a blue PROFESSIONAL banner above SURGE ARREST branding with AMERICAN POWER CONVERSION printed beneath.
Two indicator lamps labeled Protection Working and Site Wiring Fault are positioned adjacent to the power switch.
The rocker switch remains present and operational, although the molded ON/OFF markings exhibit substantial wear from long-term service.
The underside incorporates two wall-mount keyhole slots and a recessed serial-number label identifying the unit as PRO7 serial number Z94030204087.
Unlike later documented APC PRO7 examples, the documented 1994 example utilizes different branding graphics and a straight-blade attachment plug rather than the right-angle plug design observed on later documented PRO7 units.
The enclosure incorporates TVSS identification markings and suppression ratings of 330 volts for line-to-neutral, line-to-ground, and neutral-to-ground protection modes.
A molded "943" marking is present on the underside of the enclosure. The significance of this marking has not been definitively established but may represent a mold identifier, production code, or manufacturing reference.
Weight
The documented example weighs approximately 1 lb 14.8 oz (873 g), including the attached power cord.
Despite being the earliest documented APC PRO7 currently preserved by the OldSurge Archive, the 1994 example is slightly lighter than the 1998 example while remaining substantially heavier than later documented PRO7 generations.

Condition Upon Acquisition
This example exhibits cosmetic wear consistent with more than three decades of age and long-term service.
Accumulated dirt, minor discoloration, scratches, scuffs, and general handling wear were visible prior to cleaning and documentation. The rocker-switch ON/OFF markings exhibit noticeable wear and are among the most visibly worn markings observed on a documented APC PRO7.
No evidence of melting, cracking, deformation, overheating, or major physical damage was observed during external examination.
The unit was cleaned prior to detailed photography, testing, and teardown documentation.

Functional Testing
The documented example was connected to utility power and evaluated for basic functionality.
When energized, the green Protection Working indicator illuminated, indicating that surge-protection circuitry remained connected and operational at the time of testing.
The Site Wiring Fault indicator remained extinguished during testing under normal operating conditions.
Testing with a receptacle tester confirmed correct hot, neutral, and ground wiring. No open ground, open neutral, reversed polarity, or other wiring faults were detected.
The rocker switch successfully controlled power to all outlets. When switched OFF, power was removed from the outlet bank and the Protection Working indicator extinguished.
The documented example passed basic functional testing and remained operational at the time of documentation.

Teardown
Teardown commenced following completion of external documentation, measurement, photography, and functional testing.
Removal of the enclosure screws allowed the upper housing section to be separated from the base, revealing the internal outlet assembly, suppression circuitry, rocker-switch assembly, and wiring.
The internal printed-circuit board carries a ©1993 American Power Conversion copyright marking, making this the earliest suppression-board revision currently documented by the OldSurge Archive.
