Product Description

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.
