Why Choose the Mersen J212022 DIII Screw Gauge Piece?
The Mersen J212022 is a precision-engineered DIII screw gauge piece designed for use in Diazed fuse systems. As part of the established Mersen D-system ring adapter, fittings and touch protection range, it ensures that only the correct 63 A DIII fuse link can be installed in a compatible fuse base.
This screw gauge piece provides mechanical coding within the fuse base, helping prevent an incorrectly rated fuse link from being fitted. Correct fuse selection is essential for maintaining the intended overcurrent protection of electrical cables, machinery and distribution equipment.
With a 63 A current rating, DIII fuse size compatibility and standard copper identification colour, the J212022 can be quickly recognised during installation and maintenance. Its compact dimensions and robust construction make it suitable for industrial switchgear, distribution boards and electrical control panels using D-system fuse protection.
