Fuse link - NH00 gG 80A/690V - time-lag 004182313

Reliable installation protection with NH00 gG 80A/690V fuse link

This NH00 gG 80A/690V knife fuse link is a proven safety element for electrical installations, protecting against the effects of short circuits and overloads. Designed to operate in alternating current (AC) systems, it provides effective protection for wires and devices, meeting the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. Its versatility makes it suitable for both professional installers and end-users looking for reliable protection.

Construction and characteristic features

The fuse link is made of high-quality materials – a steatite body (thermally stable material), silver-plated brass knife contacts and an aluminum cover, guaranteeing corrosion resistance and long-term operation. Filling the body with quartz sand of a special granulation ensures a high short-circuit breaking capacity (up to 100 kA) and stable electrical parameters. Additionally, a combined type indicator (double) – a red eye in the central part of the ceramic body and a springy plate on the top cover – allows for quick and reliable identification of a blown fuse. This dual system increases the visibility of the fuse status in both fuse bases and disconnectors.

Application and benefits

The NH00 gG 80A/690V fuse link finds application in a wide range of industrial and energy installations. The gG characteristic means that it is a general-purpose fuse, ideal for protecting wires against overloads and short circuits. Its rated current of 80A at 690V AC makes it suitable for protecting medium-power circuits. Thanks to the use of silver-plated knife contacts, mounting is easier, and additional insulated handles (NH…/I…) ensure safety during handling. Compatibility with the NVS 5 microswitch enables remote signaling of fuse operation, increasing user comfort and allowing for a quick response in the event of a failure.
