The types and purposes of fuse classification, as well as the use of fuses, make our electricity safer. Fuses use the hot melt method to protect products. When the current exceeds the specified value, fuses use the heat generated by themselves to fuse the melt and disconnect the circuit, which is an electrical appliance. 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.

What is the resistance value of the fuse? Fuse refers to an electrical device that uses the heat generated by itself to fuse the melt and disconnect the circuit when the current exceeds the specified value. A fuse is a circuit breaker that melts the melt with the heat generated by itself after the current exceeds a specified value for a period of time, thereby causing the circuit to break; 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.

In various electronic products, the trend of setting overcurrent protection and overvoltage protection components is increasing. The main reasons for this are summarized as follows: (1) With the demand for the development of electronic products, the functionality (integration) of ICs is also becoming stronger, and their "value" is naturally becoming more noble, so it is necessary to strengthen protection.

What are the differences between fast fuses and ordinary fuses? With the rapid development of industry, industries such as power grids, new energy, and rail transit have high requirements for circuit protection. Traditional fuses are no longer suitable for high-quality and high-strength circuit protection. The secondary demand for fuses has skyrocketed, and they have been widely used and safer in the emerging new energy and rail transit industries in recent years. Let's introduce the difference between fast fuses and ordinary fuses.

What is a self-restoring fuse Self-restoring fuse is a kind of overcurrent electronic protection element, using high molecular organic polymer under the conditions of high pressure, high temperature, vulcanization reaction, adding conductive particle material, through a special process. The traditional fuse overcurrent protection can only be protected once and needs to be replaced when it is burned out, while the self-restoring fuse has the dual function of overcurrent overheat protection and automatic recovery.

The difference between DC fuses and AC fuses. With the increasing demand for DC fuses in industries, rail transit, and new energy vehicles, how to correctly select DC fuses for effective protection is a problem that users and manufacturers should take seriously. When selecting DC fuses, it is not possible to simply copy the electrical specifications and structural dimensions of AC fuses, as there are many different technical specifications and design concepts between the two, A comprehensive consideration of whether to safely and reliably cut off fault currents and prevent accidents.
