Fuses play a very important role in the safe operation of electrical equipment. In the general choice of fuse, we often use 0663.315HXSL fuses. In this paper, we will introduce the application field and working principle of 0663.315HXSL.

Application Field

0663.315HXSL belongs to HRC fuse, which has the characteristics of small size, light weight, and wide application range, so it is widely used. This kind of fuse is mainly divided into the following four categories:

• Hanging type HRC fuse: suitable for high pressure occasions. The product has a large instantaneous breaking capacity and a high breaking capacity.
• Panel type HRC fuse: Suitable for power distribution cabinets, widely used in traffic signals, urban and rural electrical systems, industrial and mining enterprises, substations and other occasions.
• Miniature circuit breaker fuse: suitable for small size and light weight occasions. It has the characteristics of small size, light weight and wide application.
• Molded case HRC fuse: suitable for places with higher requirement for safety and insulation. It is mainly used in special occasions such as elevators and air conditioners.

Working Principle

The operating principle of 0663.315HXSL is that when an overload occurs, the current passing through the fuse will cause the internal temperature to rise, and the material inside the fuse housing will melt when the temperature rises to a certain value, so that the circuit is broken, and the overload can be prevented by protecting the circuit.In addition, 0663.315HXSL requires a certain voltage and current to melt the fuse material, which means that the overload current needs to exceed the rated current in a certain time, so that the internal material of the fuse can be melted to ensure the protection.The actual breaking current and breaking time of 0663.315HXSL depends on the quality of the fuse material. In order to ensure safety, we should purchase 0663.315HXSL fuse of reliable quality, and install and use according to the relevant laws and specifications.

Conclusion

0663.315HXSL has the advantages of high breaking capacity, small size and light weight, so it is widely used in various occasions. No matter what occasion it is used, it must be used correctly and the quality of the product purchased must be reliable.
