Both are protective devices. A fuse is used one time, whereas a breaker is used multiple times.

Anonymous Answer
fuses and circuit breakers are both used as safety mechanisms in electrical circuits. They are used to stop electrical current in the event of a malfunction. The difference being a fuse has to be replaced once a malfunction occurs while a circuit breaker can be reset and reused.
