A fuse is an electrical device that uses a metallic conductor as a fusible element connected in series in a circuit. When an overload or short-circuit current passes through the fusible element, it melts due to its own heating, thus breaking the circuit. Fuses are simple in structure, easy to use, and widely used as protective devices in power systems, various electrical equipment, and household appliances.
Fuses are widely used in high and low voltage power distribution systems and control systems, as well as electrical equipment, as short-circuit and overcurrent protectors. They are specifically used in laptops, smart wearables, drones, and many other products, and are also finding applications in emerging scenarios such as AI servers, photovoltaics, energy storage, charging piles, and industrial control.
