3 Phase 60ka 3p+N AC Surge Suppressor

3 phase 3P+N - surge suppressor for protection of AC power line, DIN rail mount replaceable surge modules with 3 MOV+1 GDT module, Imax 40kA, are suitable for lightning and surge protection in AC 50/60Hz, 220/380V sub-distribution board. Features of 3 phase surge suppressor FV30C/3+NPE S:There is a thermal cutoff member inside the 3 phase surge arrester, when the device is over-current or over-voltage and the puncture is nonseviceable, the thermal cutoff member will automatically separate from the surge protective device from the electrical network, and the indication window will turn red from green. APPLICATION of 3 phase surge suppressor FV30C/3+NPE S:AC power line of building, house, bank, Telecome tower and so on.
