Answer / ilononurb
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.

Answer / abobakkar
MCCB - Miniature Current Circuit Breaker
ACB - Air Circuit Breaker
VCB - Vaccum Circuit Breaker
MCCB is used for load purpose and is should used upto 1200-
1500A only.
ACB is used for low tension (LT) panel it should carry upto
4000A and more.
VCB is used for high tension (HT) panel it means carry 11KV
and low amps rating it can withstand at long time at high
voltage also.
