What’s the Difference Between a Fuse and a Circuit Breaker?

Fuses and circuit breakers are both devices used to protect electrical systems from overloads, short circuits, and other faults. The main difference between them is how they function. Fuses are simple, disposable devices designed to melt and break the circuit when a certain current level is exceeded. They need to be replaced once they blow. On the other hand, circuit breakers are reusable devices that trip automatically when a fault is detected. They can be reset after tripping, eliminating the need for replacement. Additionally, circuit breakers are more reliable and can provide better protection than fuses, as they can trip faster and more accurately in response to faults.
