FM1L Earth-leakage Circuit Breaker (ELCB)

FM1L Earth-leakage Circuit Breaker (ELCB)

FMIL series Earth-leakage circuit breaker (ELCB) is suitable for AC 50/60Hz, rated voltage 230/400V, rated current 1-63A lines, with leakage, shock, overload, short circuit protection functions. When the leakage current exceeds the prescribed current value, the product cut off the fault current within 0.1s, protect personal safety and prevent the accident caused by the leakage current of equipment, and can be used to protect the overload and short circuit of the line. Under normal circumstances, it can be used as an infrequent disconnection and conversion of the line. It is mainly used in the protection of building lighting and distribution systems.
