Fuse

A fuse is an electrical appliance that breaks a circuit by breaking heat from the heat generated by itself when the current exceeds a specified value. A fuse is a current protector made by applying this principle after the current exceeds a specified value for a period of time to melt the melt by its own heat. Fuses are widely used in high and low voltage power distribution systems and control systems as well as in electrical equipment. As short-circuit and over-current protectors, they are one of the most popular protection devices.
