Fuses are safety devices that are designed to protect electrical circuits, equipment and components from damage due to excessive current. The 022503.5VXP is a type of fuse designed for medium-voltage applications that is capable of interrupting up to a maximum of 13,800 amps. In this article, we will discuss the application field and working principle of the 022503.5VXP fuse.

Application Field

The 022503.5VXP is a medium-voltage fuse designed for use in three-phase systems ranging from 4.167KV through 38KV. It is commonly used in utility substations and other medium-voltage applications such as wind turbine and industrial installations, primarily for over-current, short-circuit and ground-fault protection. It is available in both single and dual-element configurations. The 022503.5VXP is UL listed for use in both residential and commercial installations.

Working Principle

The 022503.5VXP is a fuse that utilizes a ceramic tube-type design, which is filled with sand. An arcing wire is threaded through the ceramic tube, and when the fuse is subjected to an excessive current, the sand melts and the arcing wire creates an arc that breaks the circuit. The arcing wire then melts, thus breaking the circuit and protecting the equipment from the excessive current. The ceramic tube can be reset after the fuse has operated, allowing the fuse to be reused.

The 022503.5VXP is designed with a positive interrupting rating of 13,800 amps and a peak let-through current of 150,000 amps. This makes it an ideal choice for medium-voltage applications where high short-circuit currents may be encountered. It is also designed with an operation time of less than 1 second, which makes it fast enough to protect sensitive equipment from damage caused by operating faults.

The 022503.5VXP also features silver-coated contacts which make it resistant to current surges, as well as a high short-circuit resistance in order to provide reliable protection.

In summary, the 022503.5VXP is a medium-voltage fuse designed for use in three-phase systems ranging from 4.167KV through 38KV. It is commonly used for over-current, short-circuit and ground-fault protection and features a positive interrupting rating of 13,800 amps and peak let-through current of 150,000 amps. It also features silver-coated contacts and a high short-circuit resistance in order to provide reliable protection.
