A » A fuse and a circuit breaker both protect electrical circuits from overloads, but they function differently. A fuse contains a metal wire that melts when overheated, breaking the circuit, and must be replaced after use. A circuit breaker, however, automatically trips to interrupt the flow of electricity and can be reset and reused, offering more convenience and better long-term cost efficiency.

A »A fuse and a circuit breaker both interrupt electrical circuits during overloads, but they differ in operation. A fuse melts and must be replaced, while a circuit breaker trips and can be reset. Fuses are often used in older systems or for specific applications, whereas circuit breakers are more common in modern installations due to their reusability.
