Difference Between Circuit Breaker And Fuse

Difference between circuit breakers and fuses, the current fuse is mainly used in some old production units and early residential neighborhoods. With the continuous development of electrical automation technology in recent years, building construction technology has also been significantly improved, and its construction requirements have been greatly improved, circuit breakers and fuses still can not be eliminated, but the type of components used by the controversy, the following we look at the role of circuit breakers and fuses in the role of what are the commonalities and differences, how to choose.

Circuit breakers. Circuit breakers can be used to distribute electrical energy, infrequent start asynchronous motors, power lines and motors, etc. to implement protection, when they occur serious overload or short-circuit and under-voltage and other faults can automatically cut off the circuit, its function is equivalent to the fuse-type switches and over-under the combination of thermal relays and so on.
