MRK 35mm² Stud Rail Terminal Block, With Cover, Grey
Onka offer great value fully encapsulated DIN rail terminals. This heavy-duty stud (bolt) connection terminal is sized for high-current power distribution circuits where standard screw or push-fit terminals aren't rated highly enough.
Supplied with a touch-safe cover over the live stud connection, plus an embedded end plate — no need to purchase separate end plates.
- M8 stud/bolt connection for 35mm² cross-section conductors, rated 125A at 1000V
- Touch-safe cover included over the terminal connection
- Embedded end plate — no separate end plate needed
Suitable for:
- 35 x 7.5mm DIN Rail (Top Hat Rail)
- 35 x 15mm DIN Rail (Top Hat Rail)
- Matches Old Onka Part Number 2322

Frequently Asked Questions
What current and voltage is this rated for?
125A at 1000V, per Onka's official datasheet.
Why a stud terminal instead of screw or push-fit?
Stud (bolt) terminals are the standard connection method for heavier power cables at 35mm² and above, where a bolted lug connection is more secure than a screw clamp. Two cable lugs can be mounted on each side of the stud.
What's the cover for?
It shields the live stud connection for touch safety once wired.
Do you stock the next size up?
Yes — see our 95mm² / 232A stud terminal for larger cable runs.
Industry Applications
- Power distribution panels — heavy-gauge incoming/outgoing feeder terminations
- Switchgear & distribution boards — bolted connections for high-current circuits
- Rail, marine & renewable energy — resilient mechanical connection where vibration resistance matters
