RESIDUAL CURRENT CIRCUIT BREAKER
Construction and Feature
Elegant appearance, cover and handle in arc shape make comfortable operation.
Contact position indicating window
Transparent cover designed to carry label
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 faultleakage 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 faultleakage current occurs and exceeds the rated sensitivity.
Independent of power supply and line voltage, and free from extemal interference, voltage fuctuation.
