Fuse link - NH1 gG 160A/690V - time-lag 004184324

Reliable installation protection with NH fuse links.

NH knife fuse links are a proven element of electrical protection, protecting against the effects of short circuits and overloads. This model, with a rated current of 160A and a voltage of 690V, is designed for demanding industrial applications. The fuse is characterized by a time-delay gG characteristic, which means it is ideal for protecting cables and devices requiring short-term overload – for example, during motor starting.

The NH1 gG 160A/690V fuse link meets the stringent standards of PN-93/E-06160 (gF), PN-IEC-269 and VDE 0636, which guarantees its reliability and safety of use. The construction with a steatite body and silver-plated knife contacts ensures thermal stability and minimizes the risk of corrosion. The fuse has a dual operating indicator – both on the top cover and in the central part of the ceramic body – which facilitates quick identification of a blown fuse.

Construction and user features:

• Time-delay gG characteristic: provides protection against overloads and short circuits, allowing for short-term exceeding of the rated current without disconnecting the circuit. This is particularly important for devices with motors or other elements generating high starting current.
• Dual operating indicator: a red eye in the ceramic body and a springy plate on the cover facilitate quick visual identification of a blown fuse, even in difficult conditions.
• High breaking capacity: up to 100 kA at AC voltage, which ensures effective protection of the installation in the event of serious short circuits.
• Made of high-quality materials: the steatite body provides thermal stability, and the silver-plated knife contacts minimize transition resistance and the risk of corrosion.
• Compliance with standards: compliance with IEC 60269-1 and IEC 60269-2 standards guarantees safety and reliability of operation.
• Indicator compatible with remote signaling: The indicator located on the top cover allows cooperation with the NVS 5 microswitch for remote signaling of fuse operation.

Applications:

NH1 gG 160A/690V fuse links are widely used in:

• industrial installations,
• electrical switchboards,
• power circuits for electric motors,
• protection of cables and electrical devices against overloads and short circuits.

Thanks to its reliability and high technical parameters, this fuse link is a solid element of protection for any electrical installation. In addition, the possibility of cooperation with a remote signaling system increases comfort of use and allows for a quick response in the event of a failure.
