SurgeArrest Panelmount 240/120V 120KA w/ Surge Counter Audible failure alarm Calls attention to a damaged surge supressor, identifying the need for service. Reduces the time protected equipment is at risk due to compromised surge suppression. Themal overload protection Prevents thermal run-away when metal oxide varistors (MOVs) become damaged, or when a continuous overvoltage condition exists. Surge counter Records the number of power surges the unit is exposed to which can be used as an indicator that the unit is providing protection as intended. A high number of surges can be an indicator of poor facility power quality and the need for additional corrective actions NEMA 3R/12 enclosure Meets the requirements of a NEMA 3R enclosure for outdoor applications, and a NEMA 12 enclosure for indoor applications. Alarm contacts Enables remote monitoring of TVSS alarm status. Replaceable individual phase modules Significantly reduces the time to repair a damaged surge protector, minimizing the time that critical loads are unprotected from transients. Protection Working Indicator SurgeArrest 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. Lightning and Surge Protection To prevent damage to your equipment from power surges and spikes. Noise Filtering 120kA SurgeArrest models contain EMI/RFI filtering to reduce line noise that can cause data loss and keyboard errors. 40kA and 80kA units do not contain noise filtering components, so they can be used with powerline networking systems (X10, HomePlug, PLC, etc.). Maximum surge current ratings 40kA, 80kA and 120kA per phase maximum surge current ratings, for all your residential, commercial and individual equipment protection needs. Catastrophic Event Protection SurgeArrest Panelmount SPDs are equipped with fuses and thermal disconnects that react quickly to protect against dangerous high and low current wiring faults as well as other catastrophic surge events. These panelmount SPDs are passive, and continue to allow power through to your home or building if any of the surge components are damaged. Status Indicator LED's LED status indicators for each phase and an audible alarm provide immediate failure notification when suppression circuitry has been damaged by a heavy strike or surge. Physical Size For easy installation inside your circuit breaker panel (40kA model) or next to your power distribution panels. (80kA and 120 kA models) Chase nipple connection Allows for mounting of the PM2X units rigidly to the side of your panelboard.
