Fuse link - NH2C gG 100A/500V - time-lag 004185214

Reliable installation protection with NH2C gG 100A/500V fuse link

This knife-type fuse link, catalog number 004185214, is a key element in protecting electrical installations from the effects of short circuits and overloads. Designed for industrial applications, it meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. Its solid construction and precise parameters ensure reliable operation in demanding conditions.

Characteristics and application

The NH2C gG 100A/500V fuse link is characterized by a rated current of 100A and a rated voltage of 500V AC. The "gG" designation indicates its versatility – it is suitable for protecting cables against overloads and short circuits. It is a time-delay fuse, which means it allows for short-term exceeding of the rated current without tripping, which is particularly important when starting devices with electric motors or other loads with high inrush current.

Construction and functionality

The fuse link is made of high-quality materials – a steatite (thermally stable material) body, silver-plated brass knife contacts and aluminum covers providing corrosion resistance. The interior is filled with quartz sand of special granulation, which guarantees a high short-circuit breaking capacity (up to 120kA) and stable electrical parameters. A key feature of this fuse link is the dual operation indicator – combined, consisting of a red eye on the ceramic body and a springy plate on the top cover. This system ensures easy and reliable identification of a blown fuse, both visually and remotely (when working with NVS 5 microswitch). This makes diagnostics and replacement quick and efficient.
