When the electrical current that passes through a fuse exceeds the limit, it burns a hole in the thin strip of metal. This stops the flow of current and it means you have a blown a fuse. Fuses need to be replaced (not reset).

When the electrical current exceeds the limit through a circuit breaker, however, the breaker trip setting opens to stop the flow of current. Breakers are re-settable by flipping the handle on the face of the breaker.
