3 Pole MCCB Under Voltage Trip Circuit Breaker 250A High Performance


UKM30L Series Earth Leakage Circuit Breaker is developed with hi-tech in 1990S with completed protection functions, high performance, smart dimension which is the ideal replacements for the olds.


Description:


UKM30L series earth leakage circuit breaker are one 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 AC50Hz/60Hz, rated voltage up to 400V, rated current16A to 630A. And is acted as infrequent changeover of circuit or infrequent starting of motor. The breaker has overload, short-circuit and under-voltage protective function, which can protect the circuit and the power equipment against damage, meanwhile, it can provide protection to these fire dangers that caused by these long-time existed grounding fault that can not be detected by the over-current protection.
