What is a common disadvantage of Circuit Breakers compared to Fuses?

Circuit breakers are a common choice for overcurrent protection in electrical systems, and one noted disadvantage compared to fuses is that they typically take up more physical space. This is primarily because circuit breakers are more complex devices that include mechanisms for manual operation, a trip mechanism, and additional components, all of which require a larger housing. In contrast, fuses are simple, compact components that can fit into tight spaces easily.

While circuit breakers offer advantages such as the ability to reset after tripping (unlike fuses which need to be replaced) and generally higher safety features, their bulkier design can be a drawback, especially in applications where space is at a premium. This aspect makes the answer relevant, as it highlights a significant design characteristic that can impact installation and space utilization within electrical panels or systems.
