Electrical, Specialty Fuses: 90EET application field and working principle

90EET fuses are special products used to replace traditional circuit breakers and other fuses to protect circuits from over-current and short circuit. As the most advanced current protection device, 90EETfuses provide better safety protection, higher over-current protection, better short-circuit protection, and are particularly suitable for strong current applications.

Application Fields

90EET fuses have wide applications in power supply, distribution control, signal transmission, etc. For example, they can be used in electric substations, transmission and distribution lines, electric energy measuring, power electronic testing, industrial machinery, motor control, and so on. All these applications need fast protection in high-voltage environment and thus 90EET fuses are the ideal solution.

Working Principle

The working principle of the 90EET fuse is simple. When a certain current passes through the fuse, the internal temperature of the fusive environment rises and the cold end of the fuse element melts and is quickly cut off from the power supply. At this time, the fuse is completely disconnected from the circuit and the over-current or short circuit protection is achieved.

This 90EET fuse can provide over-current protection for the system that needs to bear large current and short-circuit protection. It provides a fast and reliable protection. When the fuse is working, it will be activated in a very short time, such as 200ms and the current can be cut off quickly. This not only reduces system damage, but also prevents secondary disasters.

Conclusion

As we can see, 90EET fuses have wide applications in high-voltage environments and owe their popularity to their reliable over-current and short-circuit protection. They are very suitable for system with large current and fast circuit protection. The working principle is also simple and effective, achieving the goal of quick current disconnection and thus ensuring safer operation.
