Hai dear engineers,
MPCB- Motor Protection Circuit Breaker
It breaks the circuit depend upon the properties of the machine.
eg:- Set the breaking current of 10Amps in MPCB for the
Machine rating of 10Amps.
So that the machine take the starting current of 1.3 to 1.5
times from the rated.MPCB does not react here. But if the
current goes 120% to 150% based on time duration it breaks
the circuit.(overload relay supportive to machine)
MCB- Miniature Circuit Breaker.
It doesn't bother about Machine. If the Ampere goes more
than the MCB range it breaks the circuit.
Short circuit protection
(overload relay supportive to resistive, lighting load,
control circuit etc.)
