MCB means miniature circuit breaker--It is thermal &
magnetic trip device operating upto 100 A. It's range is
fixed not selectable.
MCCB means Moulded Case Circuit Breaker---It is operated
upto 1000 A and High voltage MCCB also operates on 1200 A
also...And it's range is selectable..
ELCB means Earth Leakage Circuit breaker---It is operated
on leakage current only..It is not operated on short
circuit or overload current.
RCCB means Residual Current Circuti Breaker---it's Working
principle is same as ELCb..It is also operated on Leakage
current..Main differance between it and ELCB is that it is
also operated on Short circuit current

Answer / sarath chandran
Actually RCCB and ELCB have same function, thats tripping on
leakage current(spec is in mA). The recidual device which
trip on leakage current and short ckt is called RCBO.
Above furnished def for mcb n mccb are correct

Answer / lokesh ranjith
MCB mniature ckt breaker, trips when short ckt happens upto
100A
ELCB earth leakage ckt breaker trips whn short ckt happens
& earth leakage happens
MCCB moulded case ckt breaker upto 1000A
RCCB Rasidual case ckt breaker trips both earth leakage &
short ckt avail upto 100A

Answer / abobakkar
mccb-minurate current circuit breaker it used upto 1000A,
it should withstand that capacity
mcb-miniurate ciruit breaker it used upto 63A only for
light load.
elcb-earth leakage circuit breaker it used for any leakage
current in cable, then it should trip under earth fault

Answer / jamsheer koonari
MCB means Miniature Circuit Breaker-Operated up to 100A circuits
MCCB means Moulded Case Circuit Breaker-up to 1000A
ELCB means Earth Leakage Circuit breaker-operated only for leakage current.
RCCB means Residual Current Circuit Breaker-same as ELCB which is working for both leakage and short circuit.

Answer / ardo
mccb :moulded case circuit breaker its operates up to 1200A
and have ratings or have no ratings of current selecting
mcb :miniture circuit breaker operates upto 1000A nad have
selectable current ratings
ELCB means Earth Leakage Circuit breaker---It is operated
on leakage current only..It is not operated on short
circuit or overload current.
