Low Voltage Eearth Leakage Circuit Breaker Residual Current Circuit Breaker RCCB / ELCB / RCD
Specication and Feature
- Provides protection against earth fault/leakage current and function of isolation
- High current up to 100A
- Applicable to terminal and pin/fork type busbar connection
- Contact position indication
- 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
