Earth Leakage Circuit Breakers (ELCB)
Earth Leakage Circuit Breakers (ELCBs) detects current leaks and insulation failures in the electrical circuits that would cause electrical shocks to anyone coming into contact with the circuit. There are two types of earth leakage circuit breakers—a voltage ELCB and a current ELCB.
Earth Leakage Circuit Breaker (ELCB) has the same function as the residual current circuit breaker, but they are voltage sensor devices. However, the ELCB is old technology, and it’s no more in common use. The RCCB has taken center stage since it is a current sensitive device, and it has a better advantage over ELCB.
