A plug-type fuse or a device that combines fuse and plug functions in an electrical system.
Compound of fuse (from Latin fusus, melted part) and plug (from Dutch plugge). Combined term for a fuse that fits into a socket like a plug.
The plug fuse (like Edison's 'Fusetron') was a huge innovation because people could unscrew it like a light bulb—making electrical maintenance dramatically easier than the older cartridge fuses.
