Answer Posted / raj kumar

• MCCB is used for load purpose and is should used up to 1200-1500A only.

• ACB is used for low tension (LT) panel it should carry up to 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.

• MCB is used for low current ranges, available up to 63A
