Residual Current Circuit Breaker for Earth Fault / Leakage Current Provention

Thermomagnetic circuit breakers 2p 63A earth leakage circuit breaker rccb
 
 
 
Application & Features
 
♦ Elegant appearance, cover and handle in arc shape make comfortable operation.
♦ Contact position indicating window.
♦ In case of overload to protected circuit,RCCB handle trips and stays at central position, which enables a
quick solution to the faulty line.The handle cannot stay in such position when operated manually.
♦ 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
♦ 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.
