EBS1ML Moulded Case Circuit Breaker

Function

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.
