What is one potential downside of using a fuse instead of a circuit breaker?

Using a fuse instead of a circuit breaker has the notable downside of required replacement after it has operated. When a fuse blows due to overcurrent, it permanently disconnects the circuit and must be replaced to restore functionality. This can lead to increased downtime and maintenance costs, as the personnel need to procure and install a new fuse, unlike circuit breakers, which can simply be reset after tripping.

In contrast, circuit breakers are designed for multiple uses and can be reset without any replacement needed, which can be more convenient for ongoing operations. This characteristic of fuses emphasizes the importance of planning for maintenance and inventory of replacement parts in systems that rely heavily on fuses for protection.
