ACB :Air circuit breaker is available from 400A to 6300A .
They are generally used for O/L,S/C,E/f and metering
protection.
The breaking capacity is generally 35kA/50kA/60/75KA
MCCB:Moulded case circuit breaker is available from 32A to
1600A.
They offer all the protection as offered by ACB.
However MCCB are compact when compared to ACB for
respective ratings.
MCCB are difficult to repair and life is less when compared
