Differentiate between MPCB & MCCB.
How we will deciode where to use MPCB or MCCB in the circuit & why we have to use that?

Dear sir, wherever one has to use for motor protection; then one has to go for MPCB i.e. motor protection circuit breaker. Elsewhere one can connect power supply through mccb... moulded case circuit breaker.
MPCB has got thermal element... with more narrow range, settable to set with reference to motor full load current.
