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
