Why Choose the Mersen L222167 DII Screw Gauge Piece?
The Mersen L222167 is a precision-engineered DII screw gauge piece designed for use within compatible D-system fuse bases. Manufactured by Mersen, it helps ensure that only a correctly rated DII fuse link can be installed, supporting dependable circuit protection and reducing the risk of fitting an unsuitable higher-current fuse.
This gauge insert has a rated current of 6 A and uses the standard green identification colour associated with this current rating. It is installed within a compatible DII fuse base, where its calibrated opening mechanically limits the fuse links that can be inserted into the assembly.
Designed for low-voltage electrical distribution equipment, the Mersen L222167 is suitable for panel building, switchgear maintenance and replacement applications. Its compact construction, clear colour coding and compatibility with the established D fuse system make it a practical accessory for maintaining safe and correctly configured fuse installations.

Reliable Fuse-Rating Control for DII Installations
A screw gauge piece is installed in the base of a D-system fuse holder to control which fuse-link current ratings can be fitted. The calibrated opening allows an appropriately sized fuse link to make contact while preventing incompatible higher-rated fuse links from being installed.
The Mersen L222167 provides a simple mechanical method of maintaining the intended 6 A circuit protection rating. Its green identification colour also helps engineers and maintenance personnel quickly recognise the configured current rating during inspection, installation or replacement work.
Typical Applications
- Low-voltage electrical distribution boards.
- Industrial control panels.
- Commercial switchgear assemblies.
- DII fuse-base maintenance and refurbishment.
- Machinery electrical protection systems.
- OEM panel-building applications.
