What happens when a fuse blows?

Inside the fuse, there is a metal ribbon through which all the current on the circuit passes. The ribbon is sized to match the circuit wire gauge, and if too much current passes through the ribbon, it melts through, or “blows,” and the circuit goes dead.

Can a blown fuse catch fire?

When a fuse blows or a circuit breaker trips, it’s telling you that there is too much current flowing through a wire. If the fuse or circuit breaker were not there to cut off the power to the circuit, the wire could get hot and set fire to surrounding materials.
