Why Choose the Mersen NH4ADKNIFE IEC Solid Link?

The Mersen NH4ADKNIFE is a robust IEC NH solid link designed to provide a safe and visible means of circuit isolation within low-voltage power distribution systems. Manufactured in the NH Size 4a format with a 1250 A current rating, it is intended for applications where a permanent conductive link is required instead of a fuse-link.

Manufactured by Mersen, this solid link features live gripping tags and silver-plated copper current-carrying parts to deliver excellent electrical conductivity with low power dissipation. It is fully compatible with standard NH fuse systems and can be installed in NH fuse-switch disconnectors, NH fuse bases and NH switchgear assemblies.

The NH4ADKNIFE provides an effective solution wherever a permanent link or visible isolation point is required, while maintaining the same physical dimensions as an NH4a fuse-link for simple installation and replacement.

Key Advantages

  • Provides a safe and visible means of circuit isolation.
  • 1250 A current rating for heavy-duty industrial applications.
  • Compatible with standard NH Size 4a fuse systems.
  • Silver-plated copper conductors minimise power losses.
  • Live gripping tags enable safe handling with an NH fuse handle.
  • Suitable for NH fuse bases, switch disconnectors and switchgear.

Key Features

  • Manufacturer: Mersen
  • Model: NH4ADKNIFE
  • Product type: IEC NH solid link
  • Fuse size: NH4a
  • Rated current: 1250 A
  • Silver-plated copper current-carrying parts.
  • Live gripping tags.
  • Dimensions equivalent to NH4a fuse-links.
  • Suitable for visible circuit isolation.
  • RoHS compliant.

Unlike a fuse-link, the Mersen NH4ADKNIFE functions as a permanent conductive link, allowing engineers to create a safe and visible electrical connection where overcurrent protection is not required. Its silver-plated copper construction provides excellent conductivity while minimising heat generation under high load conditions.

The solid link can also be used as a switch disconnector when installed in compatible NH fuse-switches and NH fuse bases, providing flexibility for industrial distribution systems and maintenance operations.

Typical Applications

  • Industrial power distribution.
  • NH fuse-switch disconnectors.
  • NH fuse bases.
  • Electrical switchboards.
  • Visible circuit isolation.
  • Industrial switchgear assemblies.
