Miniature Circuit Breaker

Miniature Circuit Breaker Points : Miniature Circuit Breaker, Definition, Parts of Miniature Circuit Breaker The miniature circuit breaker, although a somewhat complicated piece of mechanism is gradually occupying the place of the fuse. It is being fitted in. increasing numbers in distribution boards and consumer control units. Its action is based no the principle as fitted to control large industrial circuits, whereby a predetermined excess of current operates an electromagnet. This in turn, through a switch mechanism, automatically permits the breaking current to be lower than an equivalently rated rewireable.

1. It can be made to give a close degree of small excess of current protection. This is indirect contrast to the rewire able fuse which may be wrongly wired with a heavier gauge fuse wire, so that a larger current will flow before the wire actually blows;
2. If necessary for certain purposes the mechanism may be fitted with a time delay action.
3.; After a fault in the circuit has been cleared, the supply can very easily be restored by the simple toggle switch. Parts of Miniature Circuit Breaker 1) Circuit Breaker
