When compared to circuit breakers, fuses require less time to react when circuit breaks. No maintenance is required. Homes with electrical systems installed prior to 1965 typically use fuses as electric-overload protection. ADVANTAGES OF FUSES OVER CIRCUIT BREAKERS. It reacts quicker than the circuit breakers, and it as a hope that it won’t cause more … Fuses do not have moving parts. The advantages of Fuses includes: Fuses are cheapest form of protection available. Fuses are preferred over circuit breakers for the following reasons: 1. They also react faster than a circuit breaker, and they are believed to be more failsafe than breakers because they contain fewer moving parts. They are maintenance-free and do not require periodic checking. 2. Advantages and Disadvantages of Circuit Breakers and Fuses Fuses represent a less expensive route for overcurrent protection. Fuse is a less expensive device to protect from overcurrent. Fuses have the advantages of being inexpensive, readily available and easily replaced. They can be relied upon to protect a circuit for an indefinite time. Their disadvantages are being inadequate to safely, efficiently assume the load of many modern electrical systems and difficult to identify once blown.
