Ultra-fast fuse link DIII UQ GR 35A 500V 004323001

Ultra-fast fuse links for semiconductor protection

This fuse link model, designated DIII UQ gR 35A 500V, is a component designed to protect electrical circuits, particularly semiconductor elements. It features an ultra-fast tripping characteristic, which is crucial in applications requiring an immediate response to overvoltages and short circuits. This is especially important in power supply systems for sensitive electronic devices.

Construction and application

The DIII UQ gR 35A/500V fuse link is designed to work with devices operating at a rated voltage of up to 500V AC and 315V DC. Its construction based on IEC 60269-4 standard ensures reliable protection against the effects of overloads and short circuits. The gR class (semiconductor element protection) indicates its specialization – it is an element dedicated to protecting electronic circuits where fast disconnection in the event of a failure is a priority. The rated current value of 35A makes it suitable for protecting circuits with medium power.

Key features and benefits

• Ultra-fast tripping characteristic: ensures a lightning-fast response to overvoltages and short circuits, minimizing the risk of damage to protected devices.
• gR class: dedicated to the protection of semiconductor elements, guaranteeing optimal performance in electronic circuits.
• Short-circuit breaking capacity: up to 50kA at AC voltage and 8kA at DC voltage – a high breaking capacity value ensures the safety of the installation even in the event of serious failures.
• IEC 60269-4 standard: compliance with the international standard ensures high quality and reliability of the product.
• Top indicator: facilitates visual identification of the fuse link status – burnout.
• Compact dimensions: thanks to the DIII size, it is easy to mount in standard fuse holders.
• Power loss Pd (12W): low power loss translates to energy efficiency of the system.
• Total Joule integral switching (539 A²s): a parameter important for selecting the appropriate fuse link for a specific application, indicating the energy absorbed during short-circuit switching.

Remember to select the fuse link correctly for a specific application, taking into account the rated current, rated voltage and tripping characteristic. Correct selection will ensure effective protection of the installation and electrical devices.
