ELCB (Earth Leakage Circuit Breaker) - Types and Working
ELCB or Earth Leakage Circuit Breaker is a type of circuit breaker that is used for protection against leakage current. it breaks the circuit and 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.

Earth Leakage Circuit Breaker (ELCB): Working Principle - Electrical4U
2012年2月24日 · ELCB Definition: An Earth-leakage circuit breaker (ELCB) is defined as a device that prevents electric shocks by detecting stray voltages on electrical equipment enclosures. Voltage ELCB: Voltage ELCBs work by detecting dangerous voltage differences between equipment and earth, tripping the circuit when a threshold is exceeded.
