Answer / ektate prashant
ACB- Air circuit breaker
MCCB- Moulded case circuit breaker
Arc Quenching medium in both the breakers is air only.
The difference is ACBs are of higher capicity as compared
to MCCBs.

Answer / ashutosh
The Main Differnce in Acb & Mccb is that Acb is Used For
Higer Cureent Rating >800A While The MCCB is Used For Lower
Cureent Rating<800A

Answer / akash-ncl
ACB- AIR CIRCUIT BREAKER
MCCB-Moulded case circuit breaker
Quenching media is same for both
Protection features which consumer can set will available
with acb i.e o/c,o/c time,sc amps,sc current interrupt time
and ground fault limitings
and lost and most,
short circuit limiting capability Isc is more with acb
selection of acb/mccb depends upon device,fault
level,application and economical calculation since cost
diff is most considerable here

Answer / nagaraja
ACB-Air Circuit Breaker ,MCCB-Moulded Case Circuit Breaker.
ACB using for higher current ratings and MCCB using for
lower current ratings.
ACB works under voltage as well as over current,But MCCB
will not works Under voltage.Only over current(new mccb
having under voltage fecility also through closing coil
intrudusing)
| Is This Answer Correct ? | 4 Yes | 4 No |
Answer / rajesh tewari
acb for more then 900 amp and mccb is less then 900amp.acb
protection in short ckt .open ckt. earth fault.ground
fault.unbalanced load.and dispaly it in digital vidio
dispaly.but mccb gives us protection bnut not dispaly

Answer / vijay kumar
air circuit breaker is use to open and close the circuit at normal and fault conditions
but motor control circuit board is used to control the motor current at starting and running conditions and also phase transformation like star to delta and delta to star connection
that is the basic deffence
