OPK Series Push In Connection Rail Terminal Blocks
Onka manufacture great value fully encapsulated DIN rail terminals. The OPK Series offer unrivalled performance in push fit cable termination. This 6.0mm² version is rated 41A, for higher-current circuits where 2.5mm² or 4.0mm² terminals aren't sufficient.
- No need to purchase additional end plates - terminal has an embedded end plate
- Terminals are symmetrical - does not matter which way around they are mounted
- Accepts solid conductors or crimped ferrules - lock into place without tools
- Save time and drive down costs with fast installation and simplified accessories
Suitable for:
- 35 x 7.5mm DIN Rail (Top Hat Rail)
- 35 x 15mm DIN Rail (Top Hat Rail)
- Matches Old Onka Part Number 1522
Simple Cross Connection Method
Cross connections or commoning can be achieved using simple push in bridges. The cross connector strips can be cut down to link the correct number of terminals. This 6.0mm terminal uses the 6.0mm 10-way cross connection bridge.

Frequently Asked Questions
What cable size does this terminal accept?
6.0mm² solid or ferruled conductors, 12mm strip length, rated 41A (CE).
Do I need any tools to wire it?
No — it's a push-fit design, so conductors lock in without a screwdriver.
Can I bridge several of these together?
Yes, using the 6.0mm 10-way cross connection bridge (linked above), cut down to the number of poles needed.
Is this compatible with my existing Weidmuller or Wago terminals?
It's the same 6.0mm² size and rating as the Weidmuller WDU 6 (screw connection) and Wago TopJob S 2206-1201 (push-in connection, like this one).
How does this compare to the 4.0mm² version?
Larger cross-section for higher-current circuits (41A vs 32A) — choose based on your circuit's cable gauge.
Industry Applications
- Control panel building — heavier-gauge circuit termination in the same rail footprint
- OEM machine builders — cost-effective alternative to premium European brands without compromising rating
- Power distribution — higher-current feeds within control panels and distribution boards
