what is the technical diffrences of mccb and acb
Answer Posted / amit sonmale
MCCB can be used in the saftey of machines for LT side with
higher Amps ratings i.e.. upto 250Amps.
But ACB and VCB are used in the HT side only.
But all the three are used for short circuit trippin and
fault tripping.
ACB and VCB are highly sensitive and based on various
factors like Milliamps setting,Short circuit time etc..
