What is the Difference Between MCCB & ACB & VCB
Answer Posted / sridhar
mccb:moulded case circuit breaker used as an incomer to any
panel,mccb can be used till 1000A beyond that acb & vcb are
used,acb=>3000A at 440v low tension side
vcb=>3000A > 6.6kv,11kvat medium voltage side
sf6=>6000 > 66kv,110kvat high voltage side
