ELCB sense the earth Leakage fault in any circuit and trip
the circuit. ELCB is the same as an RCCB also sometimes
referred to as an RCD - Residual Current Device.

Answer / vipin joshi

Elcb and rccb work for same cause.. that is earth leakage they both gets trip..
But rccb have more function i.e. it get also get trip with overload..
RCcb also trip with unbalance load..
Elcb : EARTH LEAKAGE CIRCUIT BREAKER
RCCB: RESIDUAL CURRENT CIRCUIT BREAKER

I think this is enough to understand about both..

Answer / r.balu

elcb is emergency light circuit breaker it is using from
lighting circuit only.Any bady shot this breaker is trip


RCCB is nothing but MCCB it is a moulded case circuit
breaker.Its used for breading capacity generaly for shot
