What is a major advantage of using a circuit breaker over a fuse?

A significant advantage of using a circuit breaker over a fuse is that circuit breakers can be reset after tripping, which makes them more convenient and practical for ongoing use. When a circuit experiences an overload or short circuit, a fuse will blow, requiring replacement to restore functionality. In contrast, a circuit breaker can simply be switched back on after addressing the issue, allowing for quicker recovery in case of electrical faults. This feature not only saves time but also eliminates the need for carrying replacement fuses and the inconvenience of installation.

The other options, while relevant in certain contexts, don't accurately capture the primary benefit. Cost considerations can vary based on the specifics, and while newer circuit breakers may take up space effectively, this isn't universally true. Maintenance needs can also differ based on the device type and conditions, but circuit breakers typically do not require routine maintenance like fuses.
