MRK 150 mm² STUD RAIL TERMINAL BLOCK (WITH COVER) GREY
Onka manufacture high quality blocks for terminating large CSA cables on DIN Rail. Perfect for high current applications where conventional rail terminals are not suited.
Ideal for power connections in rail and mobile systems, photovoltaic (PV) and industrial applications including electrical control panels and automation.
Through terminal, both sides have an M12 threaded connection and independent hinged cover. Please note these terminals are sold individually.
✔ Secure connection for high-section cables
✔ Maximum resistance against vibration
✔ Fully insulated with its modular cover structure
✔ High resistance against mechanical stress with the bolt connection and high tightening torque
✔ Longer operational facility lifecycle and minimum voltage drops with lossless conductor structure
Matches Old Onka Part Number 2422

Frequently Asked Questions
What cable size does this accept?
150mm² CSA cable via an M12 threaded bolt connection, rated 309A at 1000V.
How is it mounted?
35mm DIN rail plus screw-to-background fixing, with an independent hinged cover on each side.
Is this sold individually or as a kit?
Sold individually — both sides have their own M12 threaded connection and hinged cover.
What applications is this suited to?
High-current power connections — rail and mobile systems, photovoltaic (PV) installations, and industrial control panels and automation.
Do you stock a smaller size?
Yes — see our 120mm² / 269A stud terminal for lighter cable runs.
Do you stock the next size up?
Yes — see our 185mm² / 353A stud terminal for larger cable runs.
Industry Applications
- Photovoltaic (PV) installations — high-current DC connections for solar arrays
- Rail & mobile systems — vibration-resistant high-current terminations
- Industrial control panels — large CSA cable termination where standard rail terminals aren't rated
