- Provides productio against earth faulth/leakagecurrent and function of solution
- High short-circuit current withstand capacity
- Applicable to terminal and pin/fork type busbar connection
- Equipped with finger protected connection terminals
- 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.
To protect the electric distribution system and electrical devices against short-circuit ()if the defect has been caused by failur or incorrect connection) and to protect the electrical distribution system against overload (if the circuit has not been damage but an extreme thermal overload occurred which could damage the wiring).
