Fuseholders

Fuseholders are used in electrical distribution systems to safely and securely hold fuses which protect against excessive currents and provide electrical isolation for the user. They are held down by a combination of screws, nuts and bolts, plus a variety of mechanical and electrical components. This article will cover the 2543100 application field and working principles of fuseholders.

2543100 Application Field

The 2543100 application field covers the use and installation of standard-sized industrial fuseholders. These are designed to accept the most common types of fuse, including those manufactured by Ferraz Shawmut, Bussmann, Littelfuse, and many others. They are available in a variety of sizes, shapes, and configurations, for use in both residential and industrial buildings. Common types of fuseholders include FUG type, DIN type, and UL approved type. They are rated for both AC and DC applications. The fuse size should be equal to or larger than the rated current of the fuseholder.

Working Principles of Fuseholders

When an electrical fault occurs, the fuseholder is designed to accept the current and safely disconnect the power from the application. The operation of the fuseholder is simple and reliable. When the fuse is inserted into the holder, the spring-loaded contact points make contact with the fuse, allowing electrical current to flow from the power source to the application. Should an excess of electrical current be detected, the fuse will blow, interrupting the flow of current and protecting the application from further damage.

In order to ensure the safe use of fuseholders, it is important to follow the manufacturer’s instructions. Most fuseholders must be properly wired, and all safety regulations must be followed. Additionally, all fuse sizes and types must be correctly matched for the particular application. The use of incorrect fuses can reduce the protection provided, and could result in damage or injury.
