Frequently Asked Questions
What cable size is this for?
4.0mm² earth/ground cable, terminated via 2 x screw terminals.
How does it mount?
Secure clip-on fitting directly to the DIN rail.
Is this compatible with my existing Weidmuller or Wago terminals?
It's the same 4.0mm² size and rating as the Weidmuller WPE 4 (screw connection, like this one) and Wago TopJob S 2004-1207 (push-in connection) — same footprint, worth checking your preferred termination method before swapping mid-panel.
What's the difference between this and the OTK 4.0mm push-fit earth terminal?
Same cable size, but this is a screw-connection version for MRK screw terminal runs; the OTK is push-fit, designed for OPK push-fit terminal runs.
