Fuse link - NH000 gG 125A/500V - time-lag 004181215

Reliable installation protection with NH000 gG 125A/500V fuse link

This knife-type fuse link, catalog number 004181215, is a proven safety element for electrical installations, protecting them from the effects of short circuits and overloads. It is an industrial component designed for reliability and long-term operation. The fuse link meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards, guaranteeing its compliance with applicable standards.

Construction and characteristic features

The NH000 gG 125A/500V fuse link is made of high-quality materials. The steatite body provides thermal stability, and the silver-plated brass knife contacts ensure good electrical contact and minimize the risk of corrosion. Aluminum covers provide additional protection against environmental influences. The fuse link is tightly filled with quartz sand of a special granulation, which translates into a high short-circuit breaking capacity – up to 120 kA.

• gG characteristic: This means full-range protection, protecting against overloads and short circuits. Ideal for general use in electrical installations.
• Dual operating indicator (KOMBI): A combination of an indicator on the top cover (resilient metal plate) and in the central part of the ceramic body (red eyelet) ensures easy and reliable identification of a blown fuse. This facilitates quick fault location and minimizes installation downtime.
• Rated voltage AC 500V: Designed for alternating current networks with a voltage of up to 500V.
• Rated current 125A: Provides effective protection for circuits with a current of up to 125A.
• Combined indicator: Allows cooperation with the NVS 5 microswitch for remote signaling of fuse link operation – particularly useful in monitoring and automation systems.

Application and installation

The NH000 gG 125A/500V fuse link is primarily used in industrial installations where reliable protection against overloads and short circuits is required. It is compatible with fuse bases and fuse disconnectors equipped with signaling microswitches. For installation, it is recommended to use insulating handles R 00-3 or GPSHE/AI, which ensure safe operation and minimize the risk of electric shock.
