What is cartridage fuse?

A cartridge fuse is a type of electrical fuse that consists of a cylindrical body with a thin metal wire or filament inside that melts when excessive current flows through it, thereby interrupting the circuit. It is typically encased in a ceramic or glass housing for protection and comes in various sizes and ratings to suit different applications. Cartridge fuses are commonly used in industrial and residential settings to protect electrical equipment from overloads and short circuits. They must be replaced once they have blown, as they cannot be reset.
