The three types of fuses are cartridge, plug, and panel.
Cartridge fuses are the most common type of fuse. They come in a variety of sizes and amperages. Cartridge fuses consist of a metal strip that is wrapped around a glass or ceramic tube filled with a heat-sensitive substance. When too much current flows through the fuse, the metal strip melts and breaks the circuit, which prevents further flow of current.
Plug fuses also come in a variety of sizes and amperages. They consist of a screw-in base with two terminals. The fuse element is a thin wire that runs between the two terminals. When too much current flows through the fuse, the wire heats up and melts, breaking the circuit and preventing further flow of current.
Panel fuses are larger than cartridge or plug fuses and are used to protect high-voltage circuits such as those found in homes or businesses. Panel fuses consist of a metal housing that contains one or more panels filled with a heat-sensitive substance. When too much current flows through the fuse, the panel melts and breaks the circuit, which prevents further flow of current
