The TE Connectivity Buchanan 796911-3 is a 3-position PCB-mount terminal block, part of the Buchanan series known for reliable screw-clamp terminations in industrial control and building automation. The green housing is a visual signature of this series, making it easy to spot on a populated PCB. It accepts wire from 12 AWG down to 30 AWG, so you can land a heavy power feed or a fine signal wire in the same block — the rising cage clamp grips the conductor without damaging it. The M3 screw is nickel-plated brass; the clamp is the same material, so there is no galvanic mismatch with copper wire. Rated 17.5 A per position at 300 V, this block handles typical panel-level power distribution inside an enclosure. The through-hole mounting keeps the block anchored during wave solder and resists the push force from screw tightening.
The screw rising cage clamp is the workhorse termination for field wiring: strip the wire, insert it into the open clamp, tighten the M3 screw to pull the cage up against the conductor. No ferrule is required, though a ferrule helps with fine-stranded wire in the 24-30 AWG range. The interlocking side feature lets you key multiple blocks together side-by-side without gaps — useful when building a multi-position strip from single-position or 3-position modules.
The 796911-3 is an active product in the Buchanan series — no last-time-buy notice, no official successor to chase. It is ROHS3 compliant, so it ships clean for EU and North American builds.
