MPCB: all the bove full form are correct.
its also an breaker with inbuilt overload protection.
as per the cordination in the panel after contactor OLR is
needed to be provided.if we are using MPCB there is no need
for overload relay.
MCB: Minature circuit breaker.
this limit it is available up to certain breaking
capacity.can be used for lower breaking capacity
