Earth leakage 意味
WebELCB or Earth Leakage Circuit Breaker is a type of circuit breaker that is used for protection against leakage current. it breaks the circuit & disconnects the power supply to the load when it senses the leakage current. The earth leakage can cause electrical shocks that can be fatal. ELCB is mainly used for protection against electrical shock. WebAC type RCD must be used for protection against AC earth leakage current. Type A. A Type RCD must be used for protection against AC and pulsating DC (rectified AC) earth leakage current. It must be installed in any circuit where the main supply is likely to be rectified. Some examples of applications where this would apply are motor speed ...
