Background
A fuse (fuse) is an electric device that fuses a fuse body by heat generated by itself when a current exceeds a predetermined value, thereby breaking an electric circuit. The fuse melts the melt by the heat generated by the fuse after the current exceeds a specified value for a period of time, so as to cut off the circuit; a current protector is made by applying the principle. The fuse is widely applied to high and low voltage distribution systems, control systems and electric equipment, and is one of the most commonly applied protection devices as a short circuit and overcurrent protector. The metal conductor is used as a melt to be connected in series in a circuit, and when overload or short-circuit current passes through the melt, the melt is fused due to self heating, so that the circuit is broken. The fuse has simple structure and convenient use, and can be widely used as a protective device in electric power systems, various electrical equipment and household appliances.
