Residual Current Circuit Breaker (RCCB, earth leakage circuit breaker) with residual operating currents 0.03A, 0.1A, 0.3A, 0.5

 

CONTRUCTION AND FEATURE

1) Provides protection against earth fault/leakage current and function of isolation.

2) High short-circuit current  withstand capacity

3) Applicable to terminal  and pin/fork type busbar connection

4) Fire resistant plastic parts endure abnormal heating and strong impact

5) Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity

6) Independent of  power supply and  line  voltage, and free from external interference, voltage fluctuation
