The HVU-3 series of Electrical Specialty Fuses provides effective protection of medium as well as high-voltage circuit applications. It is highly reliable, featuring a pressure-sensitive, thermal-magnetic action that eliminates undesired intermittent operations. The series is designed to offer a variety of safety features such as overload protection, short-circuit protection, reverse-polarity protection, and under-voltage lockout.In current field, HVU-3 series has already become the perfect fuse in medium and high-voltage circuit applications, such as power-line surge arrester, lightning arrester, and other components. It has the advantage to stop malfunctioning circuits from destructively overloading or short-circuiting.

The HVU-3\'s working principle is based on a thermal-magnetic-pressure sensitive mechanism, which is superior to standard fuses. This innovative technique enables a higher level of protection than conventional fuses, by instantaneously reacting to short-term overloading and overcurrents. The thermal-magnetic-pressure system also limits the electrical hazard to be within a reasonable and safe range.

The HVU-3 series offers two types of fuses: Bimetallic Fuses and Compound Fuses. Bimetallic Fuses are designed for operating temperatures up to 400° Celsius and are used in a variety of medium and high-voltage applications. They are constructed with a flat metal strip, which stretches and contracts due to heat generated from an overcurrent passing through the fuse. Compound Fuses are designed for higher operating temperatures and are often used in critical circuit protection. They combine both the thermal sensitivity of the bimetallic fuse and the electrical sensing of a magnetic element.

The HVU-3 series also benefits from a wide range of current ratings, ranging from 0.25 to 500 amperes. This allows the fuse to provide adequate protection in both overload and short-circuit conditions.Additionally, the HVU-3 series is environmentally friendly and fully recyclable.

In addition, the HVU-3 series has been rigorously tested and is certified to meet the highest quality and safety standards. This includes EN-60898, UL-50120, UL498, and CSA-C22.2. It has also been certified to IEC 60 255-10 and UL Standardland, and holds a CE-compliant rating.

Overall, the HVU-3 series of Electrical Specialty Fuses provides a reliable, cost-effective solution for circuit protection in a wide variety of applications. With its thermal-magnetic-pressure sensing technology and wide range of current ratings, it helps to ensure safe and reliable circuit operation. Furthermore, its environmentally friendly design and quality assurance make it a trusted and cost-effective choice for a wide range of applications.
