0460004.UR Application Field and Working Principle

Fuses are widely used in electric and electronic circuits, with a wide variety of applications to suit different needs. The 0460004.UR fuse is a current-limiting UL Class RK5 fuse manufactured by Cooper Bussmann, whose applications and working principle we will discuss in this article.

Applications of 0460004.UR Fuses

The 0460004.UR fuse is UL recognized and can be used in a variety of applications, including primary overcurrent protection of non-motor-operated appliances, motors, ballasts, starters and all other lighting and heating loads. It is also suitable for secondary distribution, providing overcurrent protection in Class RK5 branch circuits. Additionally, 0460004.UR fuses can be used as overcurrent protection of power transformers, the primary protection of building service entrances, and protection of conductor wiring circuits.

Working Principle of 0460004.UR Fuses

The 0460004.UR fuse is a current-limiting fuse, meaning that it limits the amount of current flowing through it to protect equipment and components from being overloaded. It does this by “interrupting” an overloaded circuit, creating an open circuit that prevents current from flowing. In doing so, it prevents equipment from being damaged by excess electricity.

The 0460004.UR fuse is UL Class RK5, meaning its I²t time/current characteristic is short, enabling it to react quickly and accurately in the event of an overcurrent situation. The fuse uses a fuse element made of copper-core, nickel-plated with a high thermal conductivity for maximum protection. Additionally, its corrosion-resistant housing is also made of high-tensile steel for increased strength and durability.

Furthermore, this fuse also offers superior protection against arcing and sparkover, providing an added level of safety for users. It also features a manual reset button that easily resets the fuse after a short circuit is removed, making it easier to service and maintain.

Conclusion

In conclusion, the 0460004.UR fuse is a UL Class RK5 current-limiting fuse manufactured by Cooper Bussmann that is suitable for a wide range of applications, including primary overcurrent protection of non-motor-operated appliances, motors, ballasts, starters and other lighting and heating loads. Its I²t time/current characteristic is short, enabling it to react quickly and accurately in the event of an overcurrent situation. With its corrosion-resistant housing and manual reset button, it provides superior protection against arcing and sparkover, and is easy to maintain and service.
