Fuses: 7020.9150 Application Field and Working Principle

Fuses provide both power and control for a variety of systems. The 7020.9150 fuse is used particularly in applications in which reliable, long-term protection of components, circuits, and equipment is required. This article will discuss the field of application and the working principle of the 7020.9150 fuse.

Application Field

The 7020.9150 fuse has an operational voltage rating of 690V AC, making it ideal for medium and high voltage applications. Its rated current is 160A and its interrupting rating is 10kA at 690V AC. It has excellent performance in over-currents, surge, and short circuit protection, as well as low voltage protection.

The 7020.9150 is also suitable for a variety of applications in the industrial, medical, automotive, and commercial fields. It is used in electric motors, pumps, heat exchangers, lighting, and appliances, providing essential high current protection for vital systems and devices.

Working Principle

The 7020.9150 fuse is an internal fuse type, meaning it is installed inside a device or system rather than the traditional fuse box outfitted with externally mounted fuses. This type of protection relies on heat dissipation as opposed to mechanical principles.

When the current exceeds the rated value of the fuse, the fuse wire experiences an increase in temperature. This heat melts the fuse wire, creating a high-resistance circuit which interrupts the flow of current. Once the current is interrupted, the fuse element cools and the fuse is ready to be reset.

When the internal fuse is reset, the device or system should be checked for signs of damage. The fuse may need to be replaced if it has burned out. The 7020.9150 has a self-closing contact for easy resetting without having to disconnect or replace the fuse.

Conclusion

The 7020.9150 is a highly reliable, long-term protection fuse designed for medium and high voltage applications. With a rated current of 160A and an interrupting rating of 10kA at 690V AC, it has excellent performance in over-currents, surge, and short-circuit protection. It is suitable for a variety of industrial, medical, automotive, and commercial applications. Finally, it is an internal fuse type which relies on heat dissipation to interrupt the flow of current.
