What is one of the main benefits of using circuit breakers over fuses?

• A. Better cost efficiency
• B. Easier reset capability
• C. More compact design
• D. Wider voltage capacity

Answer: (B)

One of the main benefits of using circuit breakers over fuses is the easier reset capability. Unlike fuses, which must be replaced after they blow, circuit breakers can simply be reset to restore the flow of electricity after a fault has been cleared. This convenience allows for minimal downtime since you do not need to physically replace a blown fuse; you can just switch the circuit breaker back to its operational state. This feature is particularly advantageous in environments where electrical safety and quick restoration of power are important, saving both time and resources in maintenance.

While other options may present certain advantages in different contexts—such as cost or design—none offer the operational ease and efficiency of simply flipping a switch to reset the circuit breaker.
