Fuseholders are critical components used to secure and protect electrical systems from overcurrent. The High Breakdown Field Limit Load (HEB-LL) fuseholder is an invaluable tool for ensuring system continued operation and preventing catastrophic failure within electrical circuits. This article outlines the application fiel and working principle of the HEB-LL fuseholder.

Types of HEB-LL Fuseholders

The HEB-LL fuseholder is designed specifically for use with high-power applications, such as those used in power-grid infrastructures. This type of fuseholder utilizes a specialized contact design which allows for a greater amount of current to flow through the contacts, and therefore greater protection. There are two distinct types of HEB-LL fuseholders: high-voltage and low-voltage. The high-voltage type is usually installed at a switchgear or inside an electric cabinet, while the low-voltage version can be mounted directly to the electrical equipment.

Application Field

The use of HEB-LL fuseholders in electrical systems is widespread, due to their strength and durability. These fuseholders are used in a variety of applications, such as power utilities, manufacturing plants, solar and wind energy systems, military, aerospace and medical industries. Additionally, HEB-LL fuseholders are also used in railroad, marine, and automotive applications, as well as in telecommunications and petrochemical industries.

Working Principle

HEB-LL fuseholders use a unique contact system to provide superior performance and protection compared to standard types of fuseholders. The contact system features a high-voltage contact point, which limits the voltage to a predetermined setting, protecting the system from damage due to surges of electricity. Additionally, the contact is made of a specialized brazed material which prevents oxidation and therefore eliminates the risk of failure due to wear and corrosion.

Furthermore, the fuseholders are also designed to limit arcing between the connectors due to their lower contact resistance. This reduces the amount of heat generated by the connectors and thus increases the reliability of the system. Additionally, the contact system of HEB-LL fuseholders is also designed to ensure a low fault-current, reducing the risk of fire and/or explosions caused by overcurrent.

The use of HEB-LL fuseholders is essential for the protection of electrical systems in a variety of applications. These sturdy, durable, and reliable components can withstand high currents and voltages, helping to prevent catastrophic system failure and ensuring a safe and efficient electrical system.
