HPV-DV-4A

Fuseholders are an essential part of electrical system safety and hold a fundamental role in safeguarding components from electrical surges and surges. This article will provide an overview of the HPV-DV-4A application field and working principle.

The HPV-DV-4A is a universal three-phase fuseholder that is designed to mount into distribution systems that are designed for use in hazardous areas and can accept bayonet-style fuse-links up to 4-amp. This fuseholder provides a secure and reliable connection for the fuse-link, and helps to ensure a high level of safety for the electrical installation. It is typically used in industrial applications where a high degree of safety is required, such as in factories, manufacturing plants, and power plants.

The primary function of the HPV-DV-4A is to provide a secure and reliable connection between the fuse-link and the electrical system, thereby ensuring safety. This fuseholder is unique in that it offers a tamper-proof design: the mount can only be opened with a special key, which helps to further enhance safety. Furthermore, this fuseholder is designed to be resistant to vibration and shock, as well as having a high tolerance for heat and cold.

The HPV-DV-4A is designed to be easy to install and use. It is typically fastened to the wiring system with four screws, and it is also able to accommodate cables of various sizes without needing to be engaged with additional clamps. The fuse-link itself is secured into place with a single moveable pin. The pin is designed to be ultra-secure, ensuring that the live fuse-Link is unable to be moved or accessed without the key to the holder.

When it comes to working principle, the HPV-DV-4A fuseholder works by providing a safe pathway for the electricity to travel from the power source to the wiring or components. When the fuse-link is inserted into the fuseholder, the pin inside the holder grips the fuse-link and forms a secure connection. This connection effectively creates a fuseable segment in the electrical circuit, which provides some protection from catastrophic overload, short circuits, and other hazardous situations. When the fuse-link is blown due to an overload, the pin will automatically disengage and the circuit will be interrupted, ensuring the safety of the components and preventing further damage.

Overall, the HPV-DV-4A is an excellent fuseholder that provides a secure and reliable connection between the fuse-link and the electrical system. It is designed to increase safety and is relatively easy to install and use. Due to its tamper-proof design and high tolerance for vibration, shock, heat, and cold, the HPV-DV-4A is ideal for use in hazardous areas such as factories and power plants.
