Some circuits require two wires to share one terminal block – a daisy-chained neutral, a jumped control signal, or a parallel power feed. The QUADRIOS 22C437 accepts two separate 2.5 mm² conductors in a single ferrule. Insert both stripped wires, crimp, and terminate into one screw terminal. The result is a clean, professional connection without stacking ring terminals or using two separate blocks.

The blue insulation follows DIN color coding for 2.5 mm². The 10mm pin length provides extra barrel space to accommodate two wires side by side. The polyamide sleeve resists heat up to 105°C. Use these in junction boxes, lighting control panels, or any installation where multiple wires must land on the same terminal.
