Fusibles

A fuse is a sacrificial safety device that acts as an automatic fail-safe to protect an electrical circuit from excessive current flow. A fuse’s main component is a current-conducting metal wire or strip that melts/breaks when a fault in the circuit causes it to carry more current than intended, interrupting current flow to the rest of the circuit at the expense of the fuse. A fuse’s current-conducting wire is usually enclosed in a fireproof container and must be replaced or rewired once it melts. Check out our 612 listings of Fuses today!
