Why Choose the Mersen P201769 DII Screw Gauge Piece?
The Mersen P201769 is a precision-engineered DII screw gauge piece designed for compatible D-system fuse bases. Manufactured by Mersen, this gauge insert helps ensure that only a correctly rated fuse link can be fitted, supporting reliable circuit protection in low-voltage electrical distribution systems.
Rated at 25 A, the P201769 uses the standard yellow identification colour associated with this current rating. Once installed inside a suitable DII fuse base, its calibrated opening mechanically restricts the installation of incompatible higher-rated fuse links.
The Mersen P201769 is suitable for industrial switchgear, commercial distribution boards, control panels and machinery. Its compact construction, clear colour coding and compatibility with established D-system components make it a practical choice for new installations, maintenance and fuse-base refurbishment.

Reliable Fuse-Rating Control for DII Installations
A screw gauge piece is installed inside a D-system fuse base to determine which fuse-link ratings can make contact within the assembly. This provides a simple mechanical safeguard against fitting an unsuitable higher-current fuse that could compromise the intended protection of the circuit.
The Mersen P201769 supports a correctly configured 25 A DII fuse installation. Its yellow identification colour also allows electrical contractors, panel builders and maintenance engineers to recognise the configured current rating quickly during inspection 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.
