MCB
* MCB means miniature circuit breaker.
* MCB trip current may be not adjustable in the small
ratings.
* MCB can used low current is not more then 100amps.
* MCB is used for single phase suply only.If we want mcb
for three phase suply we can use 3 mcb.
MCCB
* MCCB means moulded case circuit breaker.
* MCCB trip current may be adjustable in larger ratting.
* MCCB can used higher current areas more then 100amps.
* MCCB is used three phase suply only.
