Basic protection against power surges for computers and electronics.

Catastrophic event protection

SurgeArrest components such as MOVs and thermal fuses ensure instantaneous reaction to lightning strikes and wiring faults. If the surge components are damaged due to a power spike or overvoltage, excess power cannot reach your equipment. Unlike other surge suppressors, most surge suppressors continue to let power through even after circuits have been damaged, leaving your equipment exposed to other damaging surges.

EMI and RFI noise filtering

Reduces line noise that can cause data loss and keyboard errors.

IEEE let-through ratings and regulatory agency compliance

APC surge protectors undergo stringent testing by IEEE and are awarded "let-through ratings," which indicate the maximum voltage level that can possibly reach your equipment after a surge or voltage spike has passed through an electric surge protector. Lower IEEE let-through ratings indicate better protection and performance. The APC Essential SurgeArrest series offers optimal performance with a let-through rating of less than 330V to 500V for North American products, and a rating of less than 15% for products sold worldwide. All APC products comply with local agency safety requirements.

Protection working indicator

SurgeArrest will warn you if its circuitry has been damaged by a heavy strike or power line surge and it is unable to provide 100% protection. If still under warranty, APC will then replace your damaged SurgeArrest free of charge.
