Product Features
Surge Arrester
Surge arrester module for plug-on load center panel mounting is simple to install. Designed to fit Square D type QO Load Centers, NQO or NQOD Panelboards, or Combination Service Entrance Devices (CSED) requiring two adjacent pole spaces. Installation is completed by connecting the single white wire to the panel's neutral bar. This one device will protect your entire downstream electrical system although surge protectors are still recommended at sensitive appliances, electronic equipment and computers. Designed for use on single-phase, three-wire 120/240 Vac, 50/60 Hz electrical services. UL Listed 75YO secondary surge arrester. Also meets ANSI/IEEE C62.11-1987 requirements. Uses metal oxide varistor (MOV) design to arrest voltage surges with a low resistance path line-to-line, or line-to-neutral, or line-to-ground while providing a high resistance path to the 50/60 Hz power source. The MOV responds faster and has a lower clamping voltage than comparable gapped arresters. Individual non-replaceable internal fuse links protect each MOV and open in the event of a surge that damages an MOV. The LED on the face of the unit indicates operational status of the arrester. If the light is on the unit is fully operational. When the LED indicator goes off, the unit should be replaced. Suitable for use in service entrance locations and meets the requirements of NEC Article 280.
