A fuse is an electrical appliance that uses the heat generated by itself to fuse the melt and disconnect the circuit when the current exceeds the specified value. The fuse is based on the current exceeding the specified value for a period of time, using its own heat to melt the melt, thereby breaking the circuit; a current protector made by using this principle. Fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment. As a short-circuit and over-current protector, it is one of the most commonly used protection devices.
An electrical appliance that uses a metal conductor as a melt to be connected in series in a circuit. When an overload or short-circuit current passes through the melt, it fuses due to its own heat, thereby breaking the circuit. The fuse is simple in structure and easy to use. It is widely used as a protection device in power systems, various electrical equipment and household appliances.
