BK/ABC-BV-20-R

Fuses are devices used to protect electrical systems from overloads or short circuits. The BK/ABC-BV-20-R is a medium voltage fuse designed for use in a wide range of applications. This article will discuss the application field and working principle of the BK/ABC-BV-20-R.

Application Field

The BK/ABC-BV-20-R medium voltage fuse is designed for use in a wide variety of applications. It is a coordinated protection fuse used in three-phase circuits for the overload and short circuit protection of transformer windings, cables, and motors. It has a rated voltage of up to 20 kV and an interrupting capacity of 14.4 kA.

The BK/ABC-BV-20-R fuse can be used for the protection of branch circuits and paralleled feeders as well as individual motors, transformers, and other equipment. It is suitable for use in a variety of low-impedance systems, such as ring mains. Additionally, the fuse is also suitable for the protection of transformer banks.

Working Principle

The working principle of the BK/ABC-BV-20-R medium voltage fuse is relatively simple. The fuse is composed of a spring-loaded element and a conductor enclosed within an insulating tube. When a current higher than the nominal rating flows through the fuse, the element is heated by the electric current and the temperature of the element increases. When the temperature reaches a certain limit, the fuse element melts and the current is interrupted.

The heating of the fuse element depends on the magnitude and duration of the overcurrent. This means that the fuse can interrupt a fault current of a certain magnitude for a certain period of time, depending on the design of the fuse.

The BK/ABC-BV-20-R fuse is developed and designed for medium voltage applications and is tested in accordance with applicable industry standards. Its unique design allows for maximum safety and reliability.

Conclusion

The BK/ABC-BV-20-R medium voltage fuse is designed for use in a variety of applications, such as the protection of transformer windings, cables, and motors. It has a rated voltage of up to 20 kV and an interrupting capacity of 14.4 kA. The working principle of the fuse is relatively simple and is based on the heating and melting of the element when an overcurrent flows. The BK/ABC-BV-20-R is tested in accordance with applicable industry standards and is a reliable protection fuse.
