Fuse link - NH3C gG 355A/500V - time-lag 004186223

Knife fuse links – reliable installation protection

Knife fuse links NH are a proven element of electrical protection, protecting installations from the effects of short circuits and overloads. This model, designated NH3C gG 355A/500V, has been designed with industrial requirements in mind and meets the standards of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636. It is a key component for ensuring continuity of operation and safety in various applications.

Design and characteristic features

The NH3C gG fuse link combines a solid construction with advanced technical solutions. The body made of steatite, a material with high thermal stability, ensures reliable operation even in difficult conditions. The silver-plated brass knife contacts guarantee excellent conductivity and minimize the risk of corrosion. Aluminum covers provide additional protection against external factors. The fuse link is filled with quartz sand of a special granulation, which translates into a high short-circuit breaking capacity – up to 120 kA – and stable electrical parameters.

Particular attention is paid to the dual operating indicator: a red eye on the ceramic body and a springy plate on the top cover. This solution ensures easy and reliable identification of a blown fuse, which is important both during visual inspections and in remote monitoring systems. The indicator in the top cover enables cooperation with the NVS 5 microswitch, allowing for remote signaling of the fuse link operation.

Application and benefits

The NH3C gG 355A/500V fuse link is used to protect electrical circuits with a voltage of up to 500V AC and a rated current of 355A. It is characterized by a gG characteristic, which means that it is a general-purpose fuse link, providing full-range protection against overloads and short circuits. Thanks to this, it is perfect for protecting cables and various types of electrical equipment.
