Fuse link - NH4 gG 1250A/500V - time-lag 004116106

Reliable installation protection with NH4 gG 1250A/500V fuse link

This NH4 blade fuse link with a rated current of 1250A and a voltage of 500V is a proven safety element for electrical installations, protecting them from the effects of short circuits and overloads. Designed for AC systems, it meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards, guaranteeing reliability and safety.

The fuse link is characterized by a time-delay gG characteristic, which means it is intended for general use and effectively protects cables against overloads and short circuits.

Construction and distinguishing features

The fuse link is made of high-quality materials – a steatite body provides thermal stability, and silver-plated brass knife contacts guarantee excellent conductivity and corrosion resistance. Aluminum covers provide additional protection against external factors. The interior of the fuse link is filled with quartz sand of a special granulation, which translates into a high short-circuit breaking capacity (1250 kA) and stable electrical parameters. Equipped with a single operating indicator located on the top cover (red spring blade), it allows for quick visual identification of a blown fuse.

Application and benefits

The NH4 gG 1250A/500V fuse link finds application in a wide range of industrial and energy installations. Its solid construction and high technical parameters ensure effective protection against failures, minimizing the risk of downtime and costly repairs. The ability to cooperate with the NVS 5 microswitch allows for remote signaling of the fuse link operation, which increases the efficiency of installation status monitoring. Thanks to precise workmanship and the use of high-quality materials, the fuse link is characterized by a long service life and reliable operation.
