What is the Difference Between MCCB & ACB & VCB
Answer Posted / jitendra mahavir prasad
Mccb,Acb,vcb Is defferent according to voltage and Current . otherwise these operation is same
mccb use where the current above 100 or 63 amp and voltage lying b/w more than 240 - 1000voltage
VCB-use in LT line and its current vary between 800-10000amp but rating same as mccb.
VCB- use in HT line becoz its arch quenching capacity and insulating property high in comp to ACB.
so that is the reson which make diff bw ACB ,MCCB&VCB.
thank you
