EBS1ML series earth leakage circuit breaker are of the new type earth leakage breakers which have been developed by the company using international advanced design and manufacturing technology. Suitable for a line of AC50/60Hz,rated voltage up to 400V,rated current 16A to 630A.And it is as infrequent changeover of circuit or infrequent starting of motor.The breaker has overload,short-circuit and under-voltage protective functions,which can protect the circuit and the power equipment against damage,meanwhile,it can provide protection against fire dangerous that caused by these long-time existed grounding fault that can not be detected by the over-current protection.
