Basic Introduction to Temperature Control Fuses.lighting circuit fuse rating

　　A temperature fuse is a circuit breaker that uses the heat generated by itself to melt the melt after the current exceeds a specified value for a period of time, thereby causing the circuit to disconnect; A current protector made using this principle. Fuses are widely used in high and low voltage distribution systems, control systems, and electrical equipment. As short circuit and overcurrent protectors, they are one of the most commonly used protective devices.

　　A fuse is an overcurrent protector. The fuse mainly consists of parts such as melt, melt tube, and external filler. When in use, the fuse is connected in series to the protected circuit. When the current of the protected circuit exceeds the specified value and after a certain period of time, the heat generated by the melt itself fuses the melt, causing the circuit to disconnect, thus playing a protective role. Electrical appliances that use metal conductors as the melt to break the circuit are connected in series in the circuit. When overload or short circuit current passes through the melt, the melt itself will heat up and melt, thus providing certain protection for the power system, various electrical equipment, and household appliances. It has anti delay characteristics, and when the overload current is small, the fuse time is long; When the overload current is high, the fuse time is short. Therefore, within a certain overload current range until the current returns to normal, the fuse will not blow and can continue to be used. The fuse is mainly composed of three parts: the melt, the shell, and the support, among which the melt is a key component that controls the fusing characteristics.
