Ultra-fast fuse link DII UQ GR 30A 500V 004322008

Ultra-fast protection for your installation

DII UQ 30A/500V fuse link is a reliable protective element designed to protect electrical circuits, especially sensitive semiconductor components. Its ultra-fast tripping characteristic ensures a quick response to overvoltages and short circuits, minimizing the risk of damage and downtime.

Features and application

The DII UQ fuse link with gR characteristic (semiconductor protection) is a component intended for protecting electrical installations against the effects of overloads and short circuits. Its construction based on IEC 60269-4 standard guarantees high quality and reliability. The black housing color facilitates identification in the installation. The short-circuit switching capacity of up to 50kA (AC) and 8kA (DC) makes it suitable for use in demanding conditions.

• Fast reaction: Ultra-fast tripping characteristic protects sensitive electronic devices from damage caused by overvoltages.
• Semiconductor protection: Special gR characteristic dedicated to protecting semiconductor components.
• Versatility: Suitable for use in a wide range of electrical installations with voltage up to 500V AC and 315V DC.
• Compliance with standards: Meets the requirements of IEC 60269-4 standard, confirming its safety and reliability.
• Blow indicator: Equipped with a top indicator that facilitates quick identification of a blown fuse link.

Parameters and construction

The DII UQ fuse link is characterized by a rated current of 30A and a rated voltage of 500V AC / 315V DC. Its compact dimensions (22 x 50 x 22 mm) allow for easy mounting in standard DII fuse holders. The total Joule integral of switching is 310 A²s, which indicates its ability to absorb energy during a short circuit. Power losses are 10W, which minimizes the impact on the energy efficiency of the installation. The weight of a single fuse link is only 28g, and the basic packaging contains 5 pieces.
