ELCB is an Earth Leakage Circuit Breaker which is the same as an RCCB - a Residual Current Circuit Breaker, also sometimes referred to as an RCD - Residual Current Device.

You also get RCBOs - Residual Current circuit Breaker with Overcurrent protection, which combine the RCCB and MCB functions into one package.

If your RCCB/ELCB has tripped, there are but two possibilities : 1) It tripped on an earth leakage current, or more precisely on an imbalance between the currents in phase and neutral conductors, or 2) The device is faulty.

Answer / abdul

RCCB means Residual Current circuit Breaker.
Means the residual ce=urrent flowing in the circuits gets
activated & thte potential difference causes it to trip

Answer / arjunbel

rccb elcb
reverse current circuit earth leakage circuit breaker
breaker

it will trip a circuit it will trip source when body
whenever reverse current of equipment receives current
flows towards source I.e. due to leakage it can be preset
during short circuit to a predefined value ranging
15-100 ma
