NH Fuse Links – Reliable Installation Protection

The NH2 gG 80A/500V fuse link is an element used to protect electrical installations from the effects of overloads and short circuits. Designed for industrial applications, it meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. Its construction and parameters ensure effective protection of wires and devices, minimizing the risk of failures and downtime.

Construction and characteristic features

The fuse link is made of high-quality materials, such as steatite (body) and silver-plated brass (knife contacts). The body filled with quartz sand of a special granulation ensures stable electrical parameters and high short-circuit breaking capacity – up to 120kA. Aluminum covers protect against corrosion, guaranteeing long-term reliability.

A special feature of this fuse link is the double tripping indicator – a red eye in the central part of the ceramic body and a springy plate on the top cover. This solution facilitates quick identification of a blown fuse, both in fuse bases and in disconnectors. Additionally, the indicator on the top cover allows cooperation with the NVS 5 microswitch for remote tripping signaling.

Application and benefits

The NH2 gG 80A/500V fuse link is primarily used in:

• industrial installations: protection of power circuits for machines and equipment

• switchgear: protection against overloads and short circuits

• public buildings: ensuring the safety of electrical installations

Using this fuse link translates to:

• high reliability: solid construction and high-quality materials guarantee long-term operation

• effective protection: protection against the effects of overloads and short circuits

• easy diagnostics: double tripping indicator facilitates quick identification of a damaged fuse

• safety of use: compliance with applicable standards (IEC 60269-1, IEC 60269-2)

• convenient installation: silver-plated knife contacts facilitate mounting in a fuse base or disconnector.

It is worth remembering that the gG characteristic means full-range protection – it protects against both overloads and short circuits. Thanks to this, it is a universal solution for many applications.
