Knife fuse links – reliable installation protection

Knife fuse links NH are industrial devices designed to protect electrical installations against the effects of short circuits and overloads. Their design and electrical parameters comply with PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards, which guarantees their reliable operation and safety. This particular fuse link, with a rated current of 100A and a voltage of 400V, is characterized by a time-delay gG characteristic, which means it is intended for general use and provides comprehensive protection for conductors.

A distinguishing feature of this series is the dual tripping indicator – both a red eye on the ceramic body and a spring-loaded plate on the top cover indicate a blown fuse. This system ensures easy and quick identification of the fault, minimizing installation downtime. Additionally, the indicator on the top cover allows cooperation with the NVS 5 microswitch for remote signaling of the fuse link status.

The fuse link design is designed for durability and reliability. The steatite body provides thermal stability, and the silver-plated brass knife contacts guarantee good electrical contact and corrosion resistance. The fuse link is tightly filled with quartz sand of a special granulation, which translates into a high short-circuit breaking capacity – up to 120kA – and stable electrical parameters.

• Application: ideal for protecting electrical circuits in industry, construction and other demanding applications.
• gG characteristic: provides protection against overloads and short circuits, making it a universal solution for most installations.
• Dual tripping indicator: facilitates quick identification of a blown fuse and minimizes downtime.
• High short-circuit breaking capacity (120kA): guarantees the safety of the installation even in the event of high short-circuit currents.
• Durable construction: made of high-quality materials ensuring long life and reliable operation.
• Compliance with standards: meets the requirements of IEC 60269-1 and IEC 60269-2 standards, confirming its safety and quality.
• Power loss: is 5.8W at the rated current, which affects the energy efficiency of the installation.
• Total Joule disconnection: is 101000 A²s and arc disconnection 26000 A²s - important parameters when selecting appropriate protection for a given circuit.

The installation of the fuse link is simple and intuitive thanks to the silver-plated knife contacts facilitating its seating in the fuse base or fuse disconnector. Insulated handles (NH…/I…) are also available to provide additional protection against contact with live parts, as well as R 00-3 or GPSHE/AI insulating handles to facilitate installation.
