After hundreds of protective firings of the Arc-Plug® cartridges or after a catastrophic surge, the Arc-Plug® cartridges may fail, requiring replacement.
Alpha Delta Surge Protector Replacement Arc-Plug® Cartridges are designed to get you back up and running in no time. Failure will be apparent due to the fact that they fail in a shorted or “fail-safe” mode, so as not to leave the equipment unprotected.
Simply unscrew the failed Arc-Plug® cartridge by gripping the knurled surface and turning counter-clockwise. Make sure that the new Arc-Plug® Cartridge O-ring is fully seated into the body of the surge protector and you’re back on the air!
