Answers were Sorted based on User's Feedback
Answer / bn.abhilash kumar
the main difference is mccb means moulded case circuit
breaker which use ark
quenching device as AIR which is used upto 500 Amps only
ACB:air circuit breaker which use quenching device as air
and used upto 3000 Amps at 415 volts
Mccb is not having a long life ACB is having long life

Answer / abhilesh kumar
MCCB MEANS MOULDED CASE CIRCUIT BREAKER IT IS USED FOR ARC
QUENCHING AND MEDIUM VOLTAGE
VCB MEANS VACCUM CIRCUIT BREAKER IT IS USED FOR ARC
QUENCHING HIGH VOLTAGE
ACB MEANS AIR CB AND IT IS USED FOR ARC QUENCHING AND HIGH
VOLTAGE

Answer / pankaj kumar gupta
Mccb is moulded case circuit breaker.
ACB is air circuit breaker.
VCB is vacuum circuit breaker.
But Basic Differnce Is
Mccb use for Low value of current(16A,10A..)
Mccb depend upon Number of Pole
ACB USE FOR PROTECTION IN TRANSMISSON OF POWER IN POWER PLANT
VCB USE FOR PROTECTION IN DISTRIBUTION OF POWER IN POWER PLANT
