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.

i have faced a problem in ro plant grunfos make bm30type pump it is 22kw pump. We start this pump using siemens 3rw 4423-ibc44, 30kw softstarter but this soft starter will frequently failier so we planed to change dol starter. So pls tell anybudy its possible or not.
why the making current is more than then the breaking current and if its true then its about a controling circuit or breaker power contact points
