Fuse link - NH000 gG 25A/500V - time-lag 004181207

NH Fuse Links – Reliable Installation Protection

The NH000 gG 25A/500V fuse link is an industrial safety element designed to protect electrical installations from the effects of overloads and short circuits. It is a proven component that meets the requirements of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636 standards. The KOMBI version, equipped with a dual tripping indicator, provides quick and clear information about the blown fuse, facilitating diagnostics and replacement.

Construction and Application

The fuse link is made of high-quality steatite – a thermally stable material, which guarantees reliable operation even in harsh conditions. The knife contacts made of silver-plated brass ensure good electrical contact and minimize power losses. The body filled with quartz sand of a special granulation increases the short-circuit breaking capacity to 120kA. The main purpose of the fuse link is to protect cables in industrial installations, but thanks to the versatility of the gG characteristic, it can be used in a wide range of applications.

Advantages and Benefits

• Dual tripping indicator: A red eye on the ceramic body and a springy plate on the top cover provide a clear visual indication of a blown fuse – both in the fuse base and in the disconnector.
• High short-circuit breaking capacity (120kA): Ensures effective protection of the installation against damage caused by sudden current surges.
• gG characteristic: Universal characteristic, suitable for protecting cables against overloads and short circuits.
• Durable construction: Steatite body and silver-plated knife contacts guarantee long life and reliable operation.
• Compatibility: The fuse link is compatible with fuse bases and fuse disconnectors from various manufacturers.
• Remote signaling: Possibility of cooperation with the NVS 5 microswitch enables remote signaling of the fuse link operation, which is particularly useful in monitoring and control systems.
