From what I recall:
-MCB is a main circuit breaker, which can be any type of
circuit breaker
-MCCB is a Metal Clad Circuit Breaker, which is generally
rackable from its slot and typically used for breaking much
larger loads.

ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]
