Ultra-fast fuse link DI UQ GR 20A 500V 004321006

Ultra-fast semiconductor protection – DI UQ 20A fuse insert

This DI UQ fuse insert is a reliable protection for your electrical installations, especially for sensitive semiconductor components. Designed to react quickly to overvoltages and short circuits, it provides effective protection against damage and downtime. Its super-fast tripping characteristic (gR) makes it ideal for applications requiring high selectivity and minimal response time.

Application and design features

The DI UQ fuse insert is designed to protect circuits powering semiconductor devices such as inverters, rectifiers, and controllers. Its construction based on a ceramic body provides high resistance to environmental conditions and long-term parameter stability. The blue color of the housing makes it easy to identify and quickly recognize the insert in the installation. Dimensions DI (diameter 10mm, length 38mm) ensure compatibility with a wide range of fuse holders available on the market.

Why choose the DI UQ fuse insert?

• Super-fast tripping characteristic (gR): This means a lightning-fast reaction to short circuits, minimizing the duration of overvoltages and protecting sensitive components.
• Rated current 20A and voltage 500V: These parameters allow the insert to be used in various electrical installations of medium power.
• Complies with IEC 60269-4 standard: Guarantee of safety and reliability confirmed by a certificate of compliance with the international standard.
• Semiconductor component protection: Specifically designed to protect electronic circuits from the effects of short circuits and overloads.
• Top indicator: Allows visual control of the fuse insert status without disconnecting the circuit – after a short-circuit current flows, the indicator will change color, signaling the need for replacement.
• High short-circuit interrupting capacity: Ensures safe disconnection of the circuit in the event of a short circuit with high current.
