Fuseholders are used to hold, or "holder", different types of fuses. A fuseholder is a device that is designed to securely hold a fuse and protect it from damage, as well as offer safe insulation from electric shocks. There are numerous types of fuseholders available on the market today, each with its own unique design and features. Among the most common types of fuseholders are the HEJ-QQ variety.

HEJ-QQ holders are designed to be used primarily for medium voltage applications. They are manufactured from aluminum and offer a 20 kV insulation rating. The fuse holder consists of a base plate and an enclosure that houses the fuse, a disconnect device, and protective components. The base plate is mounted to the surface that needs to be fused, while the enclosure is bolted to the base plate. A shrink-fit insulation is then placed between the body of the fuse and the enclosure in order to achieve the necessary insulation rating.

Once the fuse holder is installed, it provides a secure environment for the fuse to be in, with a wide range of safety features to protect the fuse and surrounding equipment. It also has the ability to accommodate different types of fuses, including dual break fuses and boost-only fuses. Additionally, the HEJ-QQ holders are designed to be able to resist extreme weather conditions, ensuring that the fuse holder is protected from water and other elements.

The primary function of the HEJ-QQ holders is to provide a secure and safe environment for the fuse to operate in. In order to assure this, the holder has several features that work together to ensure safety. The primary feature is the insulating material, which is then bolted to the base plate. This provides a barrier between the fuses and the surrounding structures. Additionally, the holder\'s disconnect device provides the option to remove the fuses from service, either by manual or single button operation. This allows for quick and easy repairs and maintenance.

The base plate and disconnect device are also able to provide an arc-tolerant level of protection from inadvertent short circuits. This is achieved by using current- limiting chambers which provide a controlled release of the arc energy that occurs during short circuits. This arc-tolerant feature helps to further protect the fuse and any surrounding equipment from damage. The HEJ-QQ holder also has a wide range of features that allow for a safe and secure environment for the fuse to operate in.

Overall, the HEJ-QQ holder is designed to provide a safe and secure environment for the fuse to operate in. The wide range of features that it offers are designed to enhance the safety of the fuseholder and its surrounding equipment. Additionally, the insulating material paired with the disconnect device allows for quick and easy repairs and maintenance. All of these features make the HEJ-QQ holder an ideal choice for any medium voltage application.
