Earth leakage circuit breaker(ELCB) trips during leakage of
current from ckt. to earth.

Residual current circuit breaker(RCCB) will trip if
algebric sum of current is not be zero.

Answer / kulvinder singh, nit kurukshet

ELCB is used tirip the breaker when there is any leakage
of live current to the earth point.

RCCB-it detects the electric current is not balanced
between the energised conductor and return neutral
conductor.Such an imbalance is also caused if any human
body comes in contact with live conductor.

Answer / anoop k.liz

ELCB- ELCB will be tripped on a leakage of current from phase to earth.
RCCB- MCB+ELCB= RCCB. It will tripped on both fault current or high current and earth leakage current.

Answer / sunil kumar rakam

elcb and rccb

Answer / sandy

ELCB OPERATORS WHEN THERE IS LEAKAGE FROM PHASE TO EARTH &
RCCB OPERATORS WHEN THERE IS LEAKAGE BETWEEN TWO PHASES.

Answer / pavi

Elcb is earth leakege circuite breaker rccb is earth leakage circuite breaker

dear all, in motor operation , motor is of 100 hp and bimetal relay setting is 130 amp, if relay is getting tripped on 120 amp balance current what can be the reason? Relay is newly replaced. I dont know but is there any frequency effect in thit case? Can frequency variation affect bimetal relay operation?
