What is the Difference Between MCCB & ACB & VCB
Answer Posted / bakriwala jay
MCCB: means moulded case circuit breaker which use ark
quenching device as AIR which is used upto 500 Amps only
ACB:air circuit breaker which use quenching device as air
and used upto 3000 Amps at 415 volts
VCB:vaccum circuit breaker which use ark quenching device
as a vaccum and used for 415 volts.6.6 KV,11 KV,33 KV,132
KV,220 KV also.
