Knife fuse links – reliable installation protection

Knife fuse links NH are industrial devices designed to protect electrical installations from the effects of short circuits and overloads. Their parameters and dimensions comply with PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. This specific fuse, with the symbol NH00 gG 40A/500V, is characterized by a time-delay operating characteristic, which means 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.

This fuse is equipped with a double indication of operation – both a red eye on the ceramic body and a spring blade on the top cover indicate a blown element. This solution provides good visibility of the fuse status both in fuse bases and in disconnectors. Additionally, the indicator in the top cover allows cooperation with the NVS 5 microswitch for remote indication of operation.

The construction of the fuse is designed for durability and reliability. The body is made of durable steatite, and the knife contacts are silver-plated to ensure good electrical contact and corrosion resistance. Filling the body with quartz sand of a special granulation guarantees a high short-circuit breaking capacity (120 kA) and stable electrical parameters.

This fuse link is a solid choice for both professional installers and end-users looking for reliable protection of their electrical installations. The rated current of 40A at 500V AC makes it suitable for a wide range of industrial and commercial applications. Remember that the gG characteristic means full-range protection – it protects against overload and short circuit, which is crucial for the safety and continuity of the installation.
