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. 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 fails 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. SurgeArrest will warn you if its circuitry has been damaged by heavy strike or power line surge and it is unable to provide protection. Plug angle allows for equipment and furniture to be placed closer to the wall than with a standard power cord. It reduces cord stress too.
