JLLS400.X

JLLS400.X is an electrical component specialized in protection that is widely used in various applications. It is specially designed for the electrical and electronic circuits with high current, over-voltage and flashover protection. This type of fuse can play a decisive role in protecting the whole device and system from being damaged. In this article, we will introduce the application field and working principle of JLLS400.X.

Application Field

JLLS400.X is mainly applied in semiconductor rectifiers, inverter AC and DC drives, UPS, and thyristor AC and DC drives. It is also suitable for new energy vehicles and various types of power electronic systems, such as solar photovoltaic systems, wind power generation systems, and transmission and distribution protection equipment. With the improvement of power electronic technology, the application of JLLS400.X is becoming more and more extensive.

Working Principle

The working principle of JLLS400.X is based on the heat-sensitive characteristics of special alloy. It is composed of a bridge and a special circuit breaker assembled together. The bridge consists of special alloy wires. When the current passes through the bridge, heat is generated due to the Joule effect, and this process is repeated. The special circuit breaker is that when the temperature of the bridge exceeds the preset threshold, the bridge will be melted, and the circuit is cut off and the high current is released.

The bridge wire is designed with a higher melting point and an improved heat resistance. The circuit breaker is designed with a dual-spring cased structure, which allows for a longer lifespan and better protection, ensuring a more reliable and durable fuse. Moreover, its small size and light weight make it easy to be installed in various applications.

Conclusion

JLLS400.X is a specialty fuse with a wide range of applications in the electrical and electronic circuits. It is composed of bridge wire and special circuit breaker, and its working principle is based on the heat-sensitive characteristics of special alloy. With improved heat resistance, it can protect electric and electronic components from potential damage, ensuring reliable and durable operation.
