Introduction

Fuseholders are an important component of the electrical system, providing an efficient and reliable way to protect other device from over-current. One type of fuseholder is the BK/HKP-W-R, which is a robust, cost-effective solution for a wide variety of applications. This article will discuss the application field and working principle of the BK/HKP-W-R fuseholder.

Application Field

The BK/HKP-W-R fuseholder is well-suited to use in various industrial and commercial applications. It is an ideal choice for low voltage circuits, where it provides protection against over-current, over-voltage, and short-circuits. In addition, it can be used in high voltage applications up to 120V. Furthermore, it is especially suited for use in environments where temperature and vibration are an issue, such as automotive, medical, and telecommunications equipment.

Working Principle

The BK/HKP-W-R fuseholder is a snap-in style holder designed for easy installation and maintenance. The holder is designed with a tight-fitting cap and contact plate that securely holds the fuse in place. The contact plate is made of heat-resistant silicone rubber that is designed to provide a good electrical connection even when exposed to vibration and extreme temperatures. The holder also features a plastic dust cover that helps to prevent dust and other foreign matter from entering the holder. The BK/HKP-W-R fuseholder has two main components: a contact and a trip bar. The contact is the part of the holder that is connected to the line voltage. It consists of a copper strip or wire which is bent at an angle to provide a secure connection to the circuit. The trip bar is the part of the holder that triggers the fuse when it detects an over-current in the circuit. It consists of a movable arm that is linked to a contact spring and a trip spring. The contact spring is a metal disc which has a hole in the centre. When the arm senses an over-current, the contact spring presses against the hole in the trip bar, which causes the contact to break and the fuse to open.

Conclusion

The BK/HKP-W-R fuseholder is an effective and reliable solution for a wide range of industrial and commercial applications. It is designed to quickly and safely protect devices from over-current, over-voltage, short-circuits, and dust. Its robust design ensures a secure electrical connection, even in environments where vibration and extreme temperatures are an issue.
