Why Choose the Mersen E211512 DIII Screw Gauge Piece?

The Mersen E211512 is a precision-engineered DIII screw gauge piece designed for use in Diazed fuse systems. As part of the dependable Mersen D-system ring adapter, fittings and touch protection range, it ensures that only the correct 50 A DIII fuse link can be installed into a compatible fuse base, helping maintain safe and compliant overcurrent protection.

This screw gauge piece provides mechanical coding within the fuse base, preventing the installation of incorrectly rated fuse links. By ensuring the correct fuse rating is used, it helps preserve the intended protection of electrical circuits while reducing the risk of unsafe over-fusing in industrial and commercial installations.

With a 50 A current rating, DIII fuse size compatibility and a standard white identification colour, the E211512 is easily recognised during installation and maintenance. Its compact construction makes it suitable for distribution boards, industrial switchgear and machine control panels using Diazed fuse systems.
