3-Position Screw-Clamp Plug for Field Wiring
The 284507-3 is a TE Connectivity AMP Connectors Buchanan series plug — 3 positions, 0.150" (3.81 mm) pitch, rated 11 A at 300 V UL. It terminates stranded or solid wire from 14 to 30 AWG using a screw-driven rising cage clamp that pulls the conductor against a moving plate, not a set-screw that can nick strands. Side stacking lets you gang multiple 3-position plugs on the same header to build up circuit count without a wider single plug. Green PA66 housing carries UL94 V-0 flame rating. Tin-plated phosphor bronze contacts suit set-and-forget installations where the plug is not cycled frequently.
Wire Termination and Torque Specs
Wire entry is 180° straight into the plug — the conductor runs in line with the plug axis, which keeps the cable bundle tidy along the DIN rail or inside the junction box. Single level, 3 positions per level — each position is independent; no internal busing between positions on this plug. For commoned circuits, use a jumper bar on the mating header.
Base product number 284507 covers the series; the -3 suffix specifies the 3-position variant. No cross-reference to a different manufacturer is documented.
