difference between a fuse and a circuit breaker is simple: a fuse protects a circuit by melting a calibrated element and permanently opening the circuit, while a circuit breaker protects a circuit by tripping a mechanical switching mechanism that can usually be reset after the fault is cleared. Both devices are used for overcurrent protection, but they are not interchangeable in every application. In practice, the better choice depends on the circuit type, the need for reset convenience, the fault level, coordination requirements, equipment sensitivity, and the operating environment. For modern residential and commercial distribution, circuit breakers are usually the standard solution.
