WebThe MCB’s tripping circuit is fixed and is movable in the MCCB. MCBs have less than 100 amps, while MCCBs have as high as 2,500 amps. In MCB, the remote on/off is impossible, while in MCCB, it is possible by the use of shunt wire. The MCB is largely used in low circuit current, while MCCB is used for the heavy current circuit.
