It uses a screw-driven rising cage clamp to secure stripped wire from 12 to 30 AWG — the clamp pulls the conductor up against a nickel-plated brass contact, giving a gas-tight connection without damaging the wire strands. The 17.5 A per-position rating and 600 V voltage class suit it for industrial control panels, power supplies, and HVAC equipment where a single-level, vertical-wire block is needed. The green polyamide housing is a visual signature of the Buchanan family, making it easy to spot on a crowded board.
Wiring and Installation Details
The rising cage clamp accepts solid or stranded wire — strip length is not listed in the spec, but the M3 screw torque is specified at 0.79 Nm (7.0 Lb-In). Over-torquing can strip the nylon threads; under-torquing leaves the clamp loose. The side interlocking feature lets you snap multiple 282852-3 blocks together to build a multi-position strip without extra brackets — useful when your circuit count exceeds three and you want a clean, ganged assembly on a single PCB footprint.
