FUSES:ADVANTAGES OF FUSES OVER CIRCUIT BREAKERS

ADVANTAGES OF FUSES OVER CIRCUIT BREAKERS

Fuses are preferred over circuit breakers for the following reasons:

1. Fuses do not have moving parts. They are maintenance-free and do not require periodic checking. They can be relied upon to protect a circuit for an indefinite time.

2. In general, fuses are considered more accurate and reliable than circuit breakers.

3 A blown fuse usually provides greater incentive to correct the cause of a failure than a tripped circuit breaker.

Note: A detailed comparison between current-limiting fuses and circuit breakers is presented in the appendix. This comparison was conducted by an independent firm (Noram). The comparison describes the numerous advantages that current-limiting fuses have over circuit breakers.
