mpcb has an inbuilt contactor and relay.so need for
external contaectors and relays. mccb ther is no contactor
and relays, we have to provide.
MCB (Miniature Circuit Breaker)-rated current not more than
100 A. Trip characteristics normally not adjustable.
Thermal or thermal-magnetic operation. Breakers illustrated
above are in this
An Earth Leakage Circuit Breaker was the first name given
to what is now called a Ground Fault Circuit Interrupter
(GFCI) . The original type of ELCB or GFCI was designed
only to detect a current flowing in the safety "ground"
or "earth" wire.
A Miniature Circuit Breaker. An MCB is a device designed to
protect a circuit's wiring from the serious damage which
would be caused if it has to carry a current which is too
high for the diameter of its wires. Such a current could
easily heat up the wires so much that their insulation
melts. If that situation were allowed to develop further it
would soon cause the wires in a cable to short out and to
burn so hot that they could easily cause a house fire.
