Din Rail AC 380V Imax 40kA 220V Power Supply Surge Protector Device
DK-40 Din Rail Three Phase AC 380V Imax 40kA 220V Power Supply Surge Protector Device (SPD) is designed according to IEC61643 standard. It is accordance with the criterion of low-voltage surge protective devices-Part 1: surge protective devices performance requirements and test method of low-voltage power distribution system. With good sealing, it is designed as module and 35mm din-rail mounting. With working indication window, temperature control circuit breaker and built-in over-current protective circuit, the modular SPD can release automatically to avoid fire danger when it breaks down. With remote alarm connector, it is convenient for remote monitoring. The main module and the base are replaceable. The lightning protection modes is L-PE, N-PE (2P/4P) or L-N-PE (1+1) / (3+1).
