50/60 Hz 4 Poles 30MA 63A RCCB earth leakage Residual Current Circuit Breaker

Construction and Feature

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

High short-circuit current withstand capacity

Applicable to terminal and pin/fork type busbar connection

Contact position indication

Equipped with finger protected connection terminals

Fire resistant plastic parts endures abnormal heating and strong impact

Automatically disconnect the circuit when earth fault/ leakage current occurs and

exceeds the rated sensitivity.

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

voltage fluctuation.
