Fuse link - NH00 gG 100A/500V - time-lag 004182214

Reliable protection of electrical installations – NH00 gG 100A/500V fuse link

NH00 gG 100A/500V knife fuse link is a protective element designed to protect electrical installations from the effects of overloads and short circuits. Its construction and parameters have been adapted to operate in demanding industrial conditions, and compliance with PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards guarantees its reliability and safety of use.

Construction and characteristic 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 operation. The inside of the fuse link is filled with quartz sand of a special granulation, which affects its high short-circuit breaking capacity. This model has a double tripping indicator – a red eye on the ceramic body and a springy plate on the top cover, which facilitates quick identification of a blown fuse. The KOMBI version provides good visibility of the fuse status both in bases and in fuse disconnectors.

Application and benefits

The NH00 gG 100A/500V fuse link is used to protect circuits with time-current characteristics corresponding to the old slow-blow fuses (gG). Its rated current of 100A at 500V AC makes it ideal for protecting circuits with medium power. The short-circuit breaking capacity of 120kA guarantees effective protection of the installation against serious damage. Additionally, the double tripping indicator facilitates quick fault location and minimizes system downtime.

• Wide application: ideal for protecting circuits in industrial installations.
• High reliability: compliance with standards and solid construction ensure long-term operation.
• Quick fault identification: double tripping indicator facilitates locating a blown fuse.
• Effective protection: high short-circuit breaking capacity protects the installation against damage.
• Durable construction: corrosion-resistant materials ensure long life.
• Versatility: possibility of cooperation with NVS 5 microswitch for remote tripping indication (using the top indicator).
