Fuses

A fuse is a safety device that is used to protect electrical circuits from overloading and short-circuits. It works by breaking the flow of electrical current in the event of an overload or short-circuit. This helps to prevent damage to electrical equipment, minimize the risk of electrical fires, and protect people from electric shock.
