AllGood AG-DK-TVSS Type B Class II Box Power Supply Surge Protective Device SPD


AllGood AG-DK-TVSS Type B Class II Box Power Supply Surge Protective Device SPD is designed according to IEC61643 standard. It complys with the requirements of Low-voltage surge protective devices——Part 1: Surge protective devices connected to low-voltage power distribution systems——Requirements and tests. This product has air switch outer separating unit, working indicator lamp, malfunction indicator lamp, lightning strike counter and remote alarm signaling terminal functions. With temperature control circuit breaker and built-in over currents protective circuit, it can avoid fire danger thoroughly. The lightning protection is L-N-PE(3+1) or (2+1).

TVSS Type B is suitable for the low voltage (main) power distribution cabinet/box of buildings, and the equipment connected between three (single) phase AC power supply and system in parallel.
