DX residual current circuit breaker devices provide the function of isolation switching and earth larkage protection of electrical circuits.they open a circuit automatically in the event of an earth fault between phase and earth and /or netural and earth. A wide rang of current ratings and sensitivities are acailable.
They are suitable for domestic, commercial and industrial applications.
Residual Current Circuit Breaker(RCCB)
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
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.
