Frequently Asked Questions
What cable size is this for?
4.0mm² earth/ground cable, terminated via 2 x tool-free push-fit points.
How does it mount?
Secure clip-on fitting to the DIN rail, designed for use alongside OPK push-fit terminal runs.
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) and Wago TopJob S 2004-1207 (push-in connection, like this one) — same footprint, worth checking your preferred termination method before swapping mid-panel.
What's the difference between this and the MTK 4.0mm screw version?
Same cable size, but this is push-fit (tool-free) rather than screw connection — choose based on whether your run uses OPK (push-fit) or MRK (screw) terminals.
