Fuse link - NH2C gG 125A/400V - time-lag 004185115

Knife fuse links – reliable installation protection

Knife fuse links NH are industrial devices designed to protect electrical installations against the effects of short circuits and overloads. Their construction 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 model, NH2C gG 125A/400V, is characterized by a time-delay characteristic, which means it allows for short-term exceeding of the rated current without disconnecting the circuit. This is particularly important for devices with motors or other loads with high starting current. This fuse is designed to protect general-purpose wires and circuits (category G).

The KOMBI version, equipped with a dual operating indicator – a red eye on the ceramic body and a spring-loaded plate on the top cover – provides quick and clear information about the fuse blowing. This makes diagnostics simple and intuitive, both in fuse bases and in disconnectors. Additionally, the indicator in the top cover allows cooperation with the NVS 5 microswitch for remote tripping signaling.

• Durable construction: The body made of steatite provides thermal stability, and the silver-plated brass knife contacts guarantee excellent conductivity and corrosion resistance.
• High breaking capacity: The fuse has a short-circuit breaking capacity of up to 120 kA, ensuring effective protection of the installation in the event of serious failures.
• Safety of use: The fuse is filled with quartz sand of special granulation, which increases its breaking capacity and stabilizes electrical parameters.
• Quick diagnostics: The dual operating indicator facilitates identification of a blown fuse and speeds up the repair process.
• Compliance with standards: The product meets the requirements of IEC 60269-1 and IEC 60269-2 standards.

Installation of fuse links is facilitated by insulated holders (NH…/I…) and R 00-3 or GPSHE/AI insulating holders. Versions with a striker (NH.../K…) are also available for cooperation with HVL and KVL fuse disconnectors equipped with microswitches for remote tripping signaling.

This model is a solid solution for both professional installers and end-users looking for reliable protection of their electrical installations.
