What Mr.Rajan mantioned is not correct. Core Balance CT,
CBCT (Also called as Zero CT)is used for detecting the
earth fault current.
MCCB is a protective device by sensing the load current. By
interchanging the Phase and Neutral wires, there will not
be any difference in the load current.
So MCCB will trip on higher load current such as overload
or short circuit.
