The Buchanan NC6-P107-10 is a 10-circuit single-row barrier terminal block from the NC6 series, built for through-hole PCB mounting. It uses a dual-wall barrier design — the insulation walls between each terminal are raised on both sides, which stops wire strands from bridging adjacent positions and reduces the chance of a short when you're cinching down screws in a tight panel. The 0.375" (9.53 mm) pitch gives you enough room to land 12 AWG without fighting the adjacent terminal, while the 20 A per-circuit rating handles motor control, power distribution, and lighting circuits inside industrial cabinets.
Termination and Wiring — What You Land On
Wire range is 12-22 AWG, which covers the common power and control conductor sizes you'd run to a terminal block at 20 A. The 10 wire entries match the circuit count — one wire per position, landed under the screw head.
Ratings That Drive the Fit
The 20 A current rating at 300 V is the headline spec — it tells you this block is sized for power circuits, not signal-level duty. The 0.375" (9.53 mm) pitch is wider than the 0.325" common on smaller barrier blocks, which means the PCB footprint needs that extra spacing between rows of plated through-holes — check your board layout against the 9.53 mm centres before committing. The single-row layout keeps the block narrow, so it fits along a board edge without crowding adjacent components.
