Fuse link - NH3C gG 250A/500V - time-lag 004186219

Installation safety and protection against short-circuit effects

NH3C gG 250A/500V fuse link is an element used to reliably protect electrical installations against overloads and short circuits. Its design and parameters are adapted to operate in demanding industrial conditions, and compliance with PN-93/E-06160, PN-IEC-269 and VDE 0636 standards guarantees safety and proper operation. This fuse link is particularly recommended where protection of wires and equipment of a general nature is required.

Construction and characteristic features

The NH3C gG 250A/500V fuse link is characterized by a solid construction. It is made of high-quality steatite - a material with thermal stability, which ensures reliability even under high loads. The knife contact made of silver-plated brass provides good electrical contact and minimizes energy losses. The aluminum cover protects against corrosion, and the filling of the housing with quartz sand of a special granulation increases the short-circuit switching capacity to 120kA.

It is worth paying attention to the dual operating indicator - combined (red eye in the ceramic body and a springy plate on the cover). This solution facilitates quick identification of a blown fuse both in the fuse base and in the disconnector. Additionally, the upper indicator allows cooperation with the NVS 5 microswitch, which enables remote signaling of the fuse link operation.

Application and compatibility

The NH3C gG 250A/500V fuse link is used in industrial installations requiring protection against overloads and short circuits. It is designed to work with fuse bases and fuse disconnectors. The gG characteristic (time-delay) makes it ideal for circuits where short-term current surges occur, e.g. during the starting of electric motors. The rated voltage of AC 500V provides a wide range of applications in various electrical installations.
