The have a residual current operated electromechanical release which operates without any auxiliary source of supply to open a circuit automaticlly in the case of an earth leakage fault between phase and earth greater than or equal to a threshold of 10mA,30mA,100mA,300mA or 500mA.
1,Provides protection against earth fault/leakage current and function of isolation;
2,High breaking current withstand capacity;
3,Contact position indication;
4,Equipped with finger protected connection terminals;
5,Fire resistant plastic parts endures abnormal heating and strong impact;
6,Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity;
7,Independent of power supply and line voltage, and free from external interference, voltage fluctuation.
RCCBs/ RCDs are designed to quickly enough to mitigate the harm caused by such shocks although they are not intended to provide protection against overload or conditions.
- Simple and Robust operating mechanism.
- Rotary handle with ON/Off indication .
- Dual termination for Bus Bar as well as cable connection .
- Test Button for regular inspection.
