Fuse link - NH3C gG 125A/500V - time-lag 004186215

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 125A/500V, is designed for demanding industrial applications. Its parameters and construction comply with PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards, which guarantees its reliability and safety of use.

The fuse is characterized by a rated current of 125A at a voltage of 500V AC, and its gG characteristic indicates use in general-purpose circuits, providing comprehensive protection against overloads and short circuits. Additionally, a combined (double) operating indicator – both a red eye on the ceramic body and a spring-loaded flap on the cover – provides quick and clear information about the fuse blowing. This facilitates identification of the damage and reduces installation downtime.

The construction of the fuse has been designed with durability and efficiency in mind. The steatite body provides thermal stability, and the silver-plated brass knife contacts guarantee low transition resistance and minimize the risk of overheating. The fuse is tightly filled with quartz sand of a special granulation, which translates into a high short-circuit breaking capacity – as much as 120 kA – and stable electrical parameters during operation.

• Versatile application: Ideal for protecting cables and devices in industrial installations.
• Double operating indicator: Quick and easy identification of a blown fuse.
• High short-circuit breaking capacity: Provides effective protection even with high short-circuit currents.
• Durable construction: Steatite body and silver-plated contacts guarantee long life.
• Compliance with standards: Meets the requirements of the most important European standards (IEC 60269-1, IEC 60269-2).
• Remote signaling capability: The indicator in the upper cover allows cooperation with the NVS 5 microswitch for remote monitoring of the fuse status.

It is worth remembering the possibility of using insulated holders (NH…/I…) for additional safety during fuse replacement and insulating holders R 00-3 or GPSHE/AI for mounting in the fuse base. Choosing the right fuse link is an investment in the safety and reliability of the entire electrical installation.
