What is the different between mpcb and mcb?
*MPCB (Motor Protection Circuit Breaker) is a combination protection unit comprising the functions of a switch, a short circuit protective device and an over load relay. They are designed for various current rating to suit different capacity motors. Their quality is defined as per IS 13947 / IEC 947 MCB is only a simple circuit breaker which has only limited capability of overcurrent and short circuit current protection. *http://en.wikipedia.org/wiki/Circuit_bre… *Miniature circuit breakers (MCBs) are fitted as protection units in place of fuses. They have the advantage that they can be manually reset without having to replace wire as in the case of the traditional fuse. The MCBs have either a button or lever that can be flicked to reset it. The MCB tripping is an indication either that the circuit has been overloaded or that a short circuit has occurred somewhere in the system. Depending on their type they can r
