what is the difference between elcb,rccb,mcb.

Answer Posted / nishesh dhal

ELCB Stands for Earth Leakage Circuit Breaker,MCB stands
for Miniature Circuit Breaker & RCCB stands for Residual
Current Circuit Breaker.
In The three cases MCB was old concept which works as
circuit breaker in case of overload/short circuit.
ELCB works as a circuit braker in case of only Earth
Leakage.
But RCCB is the latest concept which works as a circuit
breaker in case of Earth Leakage,Over Load/Shor circuit.

In between three devices RCCB is the most effective circuit
breaker which does multi works How ever other two devices
doesnt work the same........
