Fuse link - NH000 UQ gR 40A/690V - ultra-fast 004331024

Professional protection for semiconductor devices

The NH000 UQ gR fuse link is a specialized solution designed to protect delicate semiconductor components from the effects of short circuits and overloads. Thanks to its gR characteristic and the ultra-fast performance of the ULTRA-QUICK series, it provides reliable protection in industrial and energy applications.

Operating parameters and performance

The device operates at a rated current of 40A and an AC voltage of 690V, allowing for use in medium-scale industrial installations. The breaking capacity is 50kA for AC and 25kA for DC, guaranteeing effective interruption even of very strong short circuits.

The gR characteristic was developed specifically for the protection of semiconductor elements, offering an optimal balance between speed of operation and selectivity. The I²t value of 1500 A²s defines the energy that the link can safely dissipate during the breaking process.

Construction and status signaling

The fuse link is made in the standard NH000 size, ensuring compatibility with widely used fuse bases. The structural dimensions are 21×79×52mm, and the total mass is only 120g, which facilitates installation and servicing.

The built-in top indicator enables quick visual inspection of the link's status - in the event of operation, the indicator changes color, signaling the need for replacement. Power losses of 11W are relatively low, minimizing additional thermal load on the installation.

Normative compliance and logistics

The product meets the requirements of the IEC 60269-4 standard, which defines detailed requirements for fuse links used in the protection of semiconductor devices. Each unit has a unique EAN code 3838895732532, facilitating identification and warehouse management.

The links are supplied in packs of 3 pieces, and the full transport package contains 120 pieces. The product's customs tariff is CN code 85361050.
