<b>Catastrophic Event Protection</b><br>SurgeArrest components such as MOVs and Thermal fuse ensure instantaneous reaction to lightning strikes and wiring faults. If the surge components are damaged due to power spike or over voltage, excess power cannot reach your equipment. Unlike the APC SurgeArrest products, most surge suppressors continue to let power through even after circuits have been damaged, leaving your equipment exposed to other damaging surges.<br><br><b>EMI and RFI noise filtering</b><br>Reduces line noise that can cause data loss and keyboard errors.<br><br><b>Fail Safe Mode</b><br>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 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.<br><br><b>IEEE let-through r This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 5310-00-638-5085, indicating validated use in U.S. government and defense logistics supply chains.
