ELCB is Earth leakage circuit breaker. It is very sensitive.
Even if there exists a minor leakage current, it will
immediately trip. Whereas RCCB is residual current circuit
breaker. It will trip only above the set trip value

Answer / k.prakashchandra

ELCB requires earth connection. Earth wire is taken through
ELCB to the body of the appliance.If there is any leakage
current in the earth wire ,it will trip.4 pole or 2 pole
RCCB requires neutral.It works on the principle that vector
sum of the currents in phases and neutral is zero or current
balancing.If there is any leakage current to the earth it
will be sensed by only phase and not the neutral resulting
in tripping.3 pole RCCB is for a 3 phase load without neutral.
