Ultra-fast fuse link DII UQ GR 20A 500V 004322006

Ultra-fast fuse links – protection for precise circuits

The DII UQ series fuse links are components designed to protect electrical circuits, especially semiconductor elements. They are characterized by a very fast response, which minimizes the risk of damage in the event of short circuits and overloads. Model DII UQ GR 20A/500V is ideal for applications requiring high selectivity and precision.

Key features and applications

A 20A rated current and 500V fuse link, made in a super-fast characteristic (gR), provides effective protection against the effects of short circuits and overloads. The gR characteristic is particularly important in circuits with semiconductor elements that are sensitive to sudden current changes. The blue color of the housing makes it easier to identify and classify in the installation. The DII size makes the fuse link compatible with a wide range of fuse holders available on the market.

• Fast response: The super-fast response characteristic (UQ) ensures almost instantaneous disconnection of the circuit in the event of a short circuit, protecting sensitive components.
• Semiconductor protection: Use of the gR characteristic dedicated to protecting semiconductor elements from the effects of short circuits and overloads.
• Versatility: Suitable for protecting various electronic and electrical systems.
• Easy identification: The blue color facilitates visual identification of the fuse link and its parameters.
• Compliance with standards: The product meets the requirements of IEC 60269 standard, guaranteeing safety and reliability.

User parameters and installation

The DII UQ GR 20A/500V fuse link has a short-circuit breaking capacity of up to 50kA AC and 8kA DC, making it suitable for high-power installations. Installation is simple and intuitive – just place the fuse link in the appropriate fuse holder. It is important to select the fuse link correctly to the parameters of the protected circuit to ensure optimal protection and avoid unnecessary shutdowns. The basic package contains 5 pieces of the fuse link, and the transport package contains as many as 500 pieces, which is important for larger installations or companies involved in the installation of electrical systems.
