125,150,175,200,215,250A Molded case earth leakage circuit breaker
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 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
The circuit breakers comply with the demands of the IEC60947

Wiring of the circuit breaker cannot be in adverse direction that
means power supply line must be connected to terminal 1, 3 and 5,
and the load line connected to terminal 2, 4 and 6.
