The 3-282836-2: It uses a screw rising cage clamp to terminate 16-30 AWG wire, with the wire entry oriented horizontally to the board — a common layout for power distribution or sensor wiring where the block sits along the board edge and wires run parallel to the PCB.
Screw Rising Cage Clamp — Torque to 0.68 Nm
The wire termination is a screw-driven rising cage clamp: turning the M3 screw lifts a nickel-plated brass clamp plate that presses the conductor against the current bar. The specified torque is 0.68 Nm (6 Lb-In) — enough to pull the wire into the cage without stripping the polyamide housing threads. The clamp and screw are both brass with nickel plating, which resists corrosion in industrial cabinet environments better than unplated steel. The contact material is brass with tin plating, adequate for the 13.5 A rating and the expected number of re-terminations in a panel.
Side Interlocking for Multi-Position Assemblies
This block includes side interlocking features, so multiple 4-position blocks can be snapped together side-by-side to create a larger multi-position terminal strip.
