An electrical device that uses metal conductors as a melt in series in a circuit. When overload or short circuit current passes through the melt, it melts due to its own heating, thereby breaking the circuit. Fuses have a simple structure and are easy to use, widely used as protective devices in power systems, various electrical equipment, and household appliances.

Fuses can be divided into high-voltage fuses and low-voltage fuses based on the voltage used. According to the protection object, it can be divided into fuses for protecting transformers and general electrical equipment, fuses for protecting voltage transformers, fuses for protecting power capacitors, fuses for protecting semiconductor components, fuses for protecting motors, and fuses for protecting household appliances. According to the structure, it can be divided into open type, semi closed type, tube type, and jet type fuses
