Earth leakage Circuit Breaker is a multi-functional protection devicesused to protect against electrical leakage in the circuit of 50/60Hz, rated voltage 230/400V,rated current up to 63A. When electirc shock happens or the residual current more than the fixed value, theleakage breakercan cut off the power within 0.1s automatically protecting the personal safety and preventing theequipmentfrom the fault resulted from the residual current.
Soit can protect the circuit against overload, short circuit and electrical leakage.
