Residual Current Circuit Breaker Earth Leakage ELCB 30 300 500mA



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.





UKM30L series residual Current Circuit Breaker (herein after called circuit breaker) is applied for the power distribution network of AC 50Hz,rated current 800A.


The circuit breaker can protect people against indirect contact with dangerous electric current and prevent fire disaster caused by insulation fault and single-phase ground fault.It can be used to distribute electric power and protect power equipment against overload and short circuit.The circuit breaker can change the circuit and start motor infrequently.


The rated residual operating current and the maximum off-time can be adjusted on-site according to actual situation,the circuit breaker can be customized alarm function and no tripping

The main purpose of earth leakage protectors is to prevent injury to humans and animals due to electric shock.





1.  Compact size, light weight and attractive frame

2.  Adapts new material, new craftwork and high insulation capacity

3.  Advanced structure

4.  Short arc-overdistance (some of the “ 0” arc-over distance) 

5.  Shake proof..
