This helps prevent damage to your equipment from electric power surges and spikes.

This LED informs users of potentially dangerous wiring problems in the wall circuit.

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.

Most other surge suppressors continue to let power through even after their circuits have been damaged, leaving your equipment exposed to future surges. APC's SurgeArrest is equipped with a fail safe, meaning that once the circuit of an APC SurgeArrest has been compromised, the unit disconnects equipment from the power supply, helping to ensure that no damaging surges reach your equipment.

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

Recovering from overloads is user-friendly with no need to replace any fuses.

Attenuates EMI/RFI line noise that can cause data errors and keyboard lockups, helping to ensure improved performance of protected equipment.

APC surge protectors undergo stringent testing by the 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 performance with a let-through rating of less than 330 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, including UL in North America and CE/Kema/Gost/C-tick/A-Tick/Telepermit in their respective regions.
