MCCB - molded case Circuit Breaker is for low voltage
application.
ACB - Air Circuit Breaker is for low and medium voltage.
VCB - Vaccum Circuit Breaker is for medium and high
voltage.
Miniature Circuit Breaker MCB is used in industrial and
domistic for low voltage with different current cap. 2 amps
up to 100 amps. this is the combination of HRC fuse and
switch. It is have thermal and magnetic tripping
protection.Which operate in the time of OL and Short
Circuit.
