Fuse link - NH2 gG 160A/500V - time-lag 004185225

Knife fuse links – reliable installation protection

The NH2 gG 160A/500V fuse link is an industrial safety element designed to protect electrical installations from the effects of short circuits and overloads. Its design and electrical parameters fully comply with the standards PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636, which guarantees its reliability and safety of use. This fuse link is characterized by a time-delay tripping characteristic (gG), which means that it allows for short-term exceeding of the rated current without disconnecting the circuit – an ideal solution for devices with motors or other loads with high inrush current.

Design and distinguishing features

The NH2 gG 160A/500V fuse link is made of high-quality materials, ensuring durability and resistance to environmental conditions. The body is made of steatite – a thermally stable material, and the knife contacts are silver-plated, which minimizes transition resistance and ensures a reliable electrical connection. It is equipped with a double tripping indicator – both in the upper cover (resilient metal plate) and in the central part of the body (red eyelet) – which facilitates quick identification of a blown fuse link. This signaling system is particularly useful in fuse disconnectors and bases, where access to the fuse link may be limited. Additionally, the ability to cooperate with the NVS 5 microswitch enables remote signaling of the fuse link operation, which increases the level of safety and monitoring efficiency of the installation.

Application and benefits

The NH2 gG 160A/500V fuse link finds application in a wide range of industrial, commercial and public utility installations. Its versatility makes it ideal for protecting cables, switchboards and other electrical infrastructure elements. Thanks to its high short-circuit breaking capacity (120kA), it provides effective protection against serious failures and equipment damage. It is worth noting its compact dimensions and ease of installation – the replacement process is quick and intuitive, minimizing downtime in installation operation. Production in the EU guarantees compliance with European quality and safety standards.
