DFJ-90-W

Specialty Fuses

The DFJ-90-W fuse is a specialty fuse used in a variety of applications in the industrial, commercial, and consumer markets. It is designed to provide a reliable, easy-to-use, and cost-effective way to protect valuable equipment from potentially dangerous electrical shocks. This article will discuss the application field and working principle of the DFJ-90-W fuse.

Application Field

The DFJ-90-W fuse is primarily used in the consumer, commercial, and industrial markets. This type of fuse is suitable for both medium and high voltage power supply systems. It is commonly used in power circuits for equipment and lighting systems, electric motors, heating systems, and contactors. Additionally, it is often used in communication systems, power supplies, household appliances, and emergency power systems such as portable generators.

Working Principle

The working principle behind the DFJ-90-W fuse is relatively simple. When an overload or short circuit occurs, the fuse element or wire inside the fuse will be vaporized by the high temperature, cutting off the power circuit and preventing current from flowing. The fuse element or wire will instantly vaporize and extinguish the arc when the current exceeds the rated current of the fuse. The fuse can be reset after the fault is cleared. The DFJ-90-W fuse is a special type of fuse that offers superior protection and reliability compared to standard fuses.

Conclusion

The DFJ-90-W fuse is a popular and reliable specialty fuse that is designed to provide maximum protection to critical electrical systems in a variety of applications. It is easy to use and cost-effective, and is capable of quickly and accurately shutting off potentially dangerous currents in the event of an overload or short circuit. Its simple working principle of vaporizing the element or wire inside the fuse when the current goes beyond the rated value makes it a highly reliable choice for power circuits, communication systems, electric motors, and other types of equipment.
