## Long description

STAN-MET NH1 250A knife-type installation clamp ZW-NH1 for NH fuses is a compact electrical accessory designed to hold and conduct current for NH1 fuse links in distribution boards and industrial switchgear. The clamp provides a stable mechanical mounting and reliable electrical contact for NH fuses rated up to 250 A, enabling secure fuse replacement and dependable current transfer in low- and medium-voltage installation panels. Its construction is intended for use where NH fuse holders and standardized knife contacts are required.
Advantages
The knife-type design ensures quick insertion and removal of NH fuse links while maintaining consistent contact pressure. Constructed to provide good conductivity and mechanical stability, the clamp reduces the risk of arcing and overheating at the connection point. Its compact size allows installation in confined spaces inside distribution cabinets and industrial enclosures. The unit is compatible with standard NH1 fuse geometry, facilitating interchangeability and straightforward maintenance.
Suitable for
Mounting NH1 fuse links in distribution boards
Use in industrial electrical cabinets and control panels
Replacement of worn or damaged knife contacts in NH fuse holders
Applications requiring reliable current transfer up to 250 A
Key specifications
Rated current: 250 A
Contact type: knife/contact blade for NH1 fuse links
Intended mounting: installation clamp for fuse holders and panels
Compatibility: designed for NH1 fuse geometry and standardized NH fuse links
Construction: compact mechanical contact intended for electrical conductivity and stability
How to use
Install the knife clamp in the designated slot or mounting point inside the fuse holder or distribution panel, ensuring the clamp body is securely fixed to the panel structure. Insert the NH1 fuse link onto the knife contact until it seats fully and verify firm mechanical contact. For removal, isolate the circuit and withdraw the fuse link by pulling it off the knife contact. Inspect contact surfaces periodically for signs of corrosion, wear or overheating and replace the clamp if mechanical integrity or conductivity is compromised.
Usage recommendations
Use only with NH1 fuse links and within the rated current limit of 250 A. Ensure all work is performed with the circuit de-energized and follow applicable electrical safety standards. Regular inspection and cleaning of contact surfaces will help maintain low contact resistance and reliable operation.
