Question { Siemens, 184747 }

what is the difference in MCB, MCCB, RCCB, ELCB, & MPCB
(motor protection circuit bracker)

Answer

mcb Miniature circutebraker will 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 braker is for
protect over load
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.
