Answer Posted / deep
As said by Naveen -
MCB = Miniature Circut Breaker.
i.e in case of over load (higher that the nominal current)
is drwan by the load the MCB trips (opens the circuit).
However, Naveen is wrong in defining ELCB & RCCB.
ELCB = Earth Leakage Circuit Breaker
RCCB = Residual Current Circuit Breaker
Both ELCB & RCCB are synonymous; the function being only
earth leake protection (and no over load protection)
i.e ELCB a.k.a RCCB trips in case there is an earth leakge
on the load side.
