mccb is protectve divise over load and shotr ckt,dipinding
ka rating of the mccb supose 25 ka mcc using this mccb
withastading ofthe current up to 25ka .u whant when phase
and nutrul shotr downstrim side using the mcb this will
trip u what to nutrul protect or earth fualt u can use cbct
incomming side of the mccb with shunt coil in side the mccb
