Word Origin and History for blow a fuse
1680s, "to melt" (transitive), back-formation from fusion. Intransitive sense, "to become liquid," attested from 1800. Figurative sense of "blend different things" is first recorded 1817. Related: Fused; fusing.
"combustible cord or tube for lighting an explosive device," also fuze, 1640s, from Italian fuso "spindle" (so called because the originals were long, thin tubes filled with gunpowder), from Latin fusus "spindle," of uncertain origin. Influenced by French fusée "spindleful of hemp fiber," and obsolete English fusee "musket fired by a fuse." Meaning "device that breaks an electrical circuit" first recorded 1884, so named for its shape, but erroneously attributed to fuse (v.) because it melts.
- A safety device that protects an electric circuit from becoming overloaded. Fuses contain a length of thin wire (usually of a metal alloy) that melts and breaks the circuit if too much current flows through it. They were traditionally used to protect electronic equipment and prevent fires, but have largely been replaced by circuit breakers.
- A cord of readily combustible material that is lighted at one end to carry a flame along its length to detonate an explosive at the other end.
- To melt something, such as metal or glass, by heating.
- To blend two or more substances by melting.
