3 Modes of protection (L-N : L-G : N-G)The remaining modes continue to provide protection in the event a mode of protection is compromised as a result of a surge.EMI and RFI noise filteringReduces line noise that can cause data loss and keyboard errors.Power Line Communications (PLC) compatibleProtects PLC network adapters without interrupting network communications.Fail Safe ModeMost 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.Protection Working IndicatorSurgeArrest will warn you if its circuitry has been damaged by 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.180 degree Rotating Cord RetainerA 180-degree rotating cord with strain relief offers flexibility in positioning the SurgeArrest, and in routing the power cord.Safety-agency approvedEnsures the product has been tested and approved to work safely with the connected service provider equipment and within the specified environment.Building Wiring Fault IndicatorThis LED informs users of potentially dangerous wiring problems in the wall circuit.Lightning and Surge ProtectionTo prevent damage to your equipment from power surges and spikes.SurgeArrest Essential Featuress & BenefitsProtectionLightning and Surge ProtectionTo prevent damage to your equipment from power surges and spikes.IEEE let-through ratings and regulatory agency complianceStringent third-party testing gives you confidence that APC's surge protectors will safeguard your equipment and data from potentially damaging surges and spikes.Noise FilteringAttenuates EMI/RFI line noise that can cause data errors and keyboard lockups, ensuring better performance of protected e
