Fuses are fundamental safety devices that protect electrical circuits by interrupting the flow of excessive current. When a fault or overload occurs, the fuse element melts, breaking the circuit and preventing potential damage and fire hazards.

Utilized across various sectors, including automotive, industrial, and consumer electronics, fuses play a vital role in safeguarding electrical components and ensuring reliable system operation. Their ease of installation and replacement makes them a practical choice for overcurrent protection.

Leading manufacturers such as Littelfuse, Eaton, and Bussmann produce a wide array of fuses, including fast-acting, slow-blow, and resettable types. Available in different current and voltage ratings, these fuses cater to the specific protection needs of diverse applications, ensuring optimal performance and safety.
