Answer / jessy
All these are circuit breakers of different Current Ranges.
mcb is used for low current ranges, avaiable uo to 63A
mccb is used for medium current ranges up to 3200 A
acb is used for more higher ratings.

MCB - Miniature circuit breaker is used from 1A to 100 Amps
rating. which is only magentic tripping device
MCCB - Moulded circuit breaker is used from 32amps to
1600amps ( combination of both thermal and magentic
tripping)
ACB - Air circuit breaker is used from 630amps to 5000amps
capacity - in older version only thermal tripping only. now
a days it is combination of both thermal and magnetic
tripping

Answer / prasad
there are so may circuit breakers, depends upon their ratings
we use up to 63A as mcb and above this current we use mccb or
acb.
acb means air circuit breaker

Answer / mani777
mcb.......o.5 to 63amp
mccb......upto ...1600 amp
acb(air circuit breaker) used in big transformer...hence
for more amps

Answer / ram
please correct long form of mccb, it is moulded case
circuit breaker.
all are the different types of ckt bkrs & are used
according to the load in amps.

Answer / dan
MCB - miniture circuit breaker
MCCB - molded case circuit breaker
acb - air circuit breaker
MCB are upto ~60 amp
MCCB are from 60 amp to thousands amp
ACB are for huge power stations thousands of amps.

mcb-miniature circuit breaker- 6amp to 63amp
mccb-moulded case circuit breaker- upto 1600amp
acb- air circuit breaker- above 1600amp

Answer / ankush dhiman
mcb (miniature ckt. breaker) is used for low current
ranges, avaiable uo to 63A
mccb (miniature current ckt breaker )is used for medium
current ranges up to 800 A
acb (air ckt breaker)is used for more higher ratings.
