MPCB is meant for motor protection only where as MCCB is for various application including Motor.
In MPCB we do not talk about Ics / Icu no cat. Configuration - class A / class B type of breakers.
For TYpe -2 Coordination we need to have external devices like -- contactor, o/l relay, contactor etc. with MCCB while with MPCB we have inbuilt configuration of Type -2 coordination (no external device)
