Fuse link - NH000 gG 35A/400V - time-lag 004181109

Knife fuse links – reliable installation protection

Knife fuse links NH are industrial devices used 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 of use. This particular fuse link, designated as NH000 gG 35A/400V, is particularly useful in applications requiring a delayed response to current flow.

Characteristics and application

The NH000 gG 35A/400V fuse link is characterized by a rated current of 35A and a rated voltage of AC 400V. The designation "gG" indicates its versatility – it is suitable for protecting conductors against overloads and short circuits. The time-delay characteristic (g) allows for short-term exceeding of the rated current without disconnection, which is important when starting devices with motors or other pulsed loads. This minimizes the risk of unnecessary circuit disconnection during normal operation.

Construction and additional features

The fuse link is made of high-quality materials: a steatite body (thermally stable material), silver-plated brass knife contacts and an aluminum cover – which ensures corrosion resistance and long-term reliability. The fuse link is equipped with a double indication of operation – a red eyelet in the central part of the ceramic body and a springy plate on the upper cover, which facilitates quick identification of a blown fuse. Additionally, the indicator in the upper cover enables cooperation with the NVS 5 microswitch for remote signaling of operation. The fuse link has an AC short-circuit breaking capacity of 120kA and an integral short-circuit energy limiting capacity of 10033 A²s. The body is tightly filled with quartz sand of a special granulation, which ensures high breaking capacity and stability of electrical parameters.
