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 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

RCCB 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, RCBO 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.
RCBO handle can be locked either at “ON” position or at“OFF” position to prevent unwanted operation of the product.
Provides protection against earth fault/leakage current, short-circuit and overload
High short-circuit capacity
Provides complementary protection against direct contact by human body.
Effectively protects electric equipment against insulating failure
Contact position indication
Provides protection against over-voltage
