Product Detail

Model No.: UKM30L-250S 4P

125,150,175,200,215,250A Molded case ear

125,150,175,200,215,250A Molded case earth leakage circuit breaker 4 Poles

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:

The ELCB is applied in the power system of AC 50Hz, rated voltage up to 400V and rated current up to 400A, for power distribution and protecting Power system from overload, short circuit, faults damage etc. it also can be used to control infrequent operation.

The rated residual operating current In and the maximum breaking time can be adjusted on site according to practical condition.

The leakage protection module still can work normally when the phase voltage reduce to 50V. It has the same overall size with the UKM30L series circuit breakers, which make the installation more exchangeable.

The circuit breakers comply with the demands of the IEC60947 standards.
