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.
