What is the Difference Between MCCB & ACB & VCB
Answer Posted / kareem
1. MCCB: - is Moulded case circuit breaker.
2. ACB: - is air circuit breaker.
3. VCB: - is vacuum circuit breaker.
.All is of different type with same
Functioning.
.All of them are used to isolate the power or to trip the
Power at the time of fault in line and thus save the
Circuit from further damage and isolate unhealthy part from
Healthy one,
1. MCCB is stand for moulded case circuit breaker. It is
for
Medium voltages.......
2. ACB:-air circuit breaker which use quenching device as
air and used up to 3000 Amps and used up to 11KV to
33KV......
3. VCB:-vaccum circuit breaker which use ark quenching
device as a vaccum and used from up to 33KV to 220KV....

Can any one provide the inspection procedure of MIMIC for VFD panel? Details: If someone wants to have a mimic in the VFD panel what are inputs considered for the mimic(like on,off,trip) whether we are able to add speed variation in the mimic(if so how can we get) and what are the parameters to be checked in the MIMIC during inspection?
