SurgeArrest components such as MOVs and thermal fuse ensure instantaneous reaction to lightning strikes and wiring faults. APC's SurgeArrest fail safe, which means that once the circuit of an APC SurgeArrest has been compromised the unit disconnects equipment from the power supply ensuring that no damaging surges reach your equipment. It attenuates EMI/RFI line noise that can cause data errors and keyboard lockups, ensuring better performance of protected equipment. SurgeArrest will warn you if its circuitry has been damaged by heavy strike or power line surge and it is unable to provide protection.
