Cartridge Fuses

Cartridge Fuses Graphic The cartridge type fuse gets its name from the shape of the container protecting the fuse link. Instead of screwing the fuse into a base, a cartridge fuse snaps or squeezes in between two holders on each end of the fuse. The ends of the cartridge fuse are metal and connect to the fuse link inside the cartridge. Larger current cartridge fuses commonly have a bayonet end that fits snugly between the jaws of special holders. Many older cartridge fuses were made with replaceable fuse elements so if the fuse link "blew" it could be replaced. The use of replaceable fuse links has largely been eliminated to reduce the chance of installation of an oversized link and overfusing.
