The Molex 0387068006 is a 3-circuit barrier terminal block from the Beau 38706 series. It is a dual-row, through-hole component with 0.325" (8.26 mm) pitch between centers — wide enough for 12-22 AWG wire and the 20 A per-circuit rating. The dual-wall barrier (2 Wall) isolates each terminal position, which matters when you are routing power wiring in an industrial control panel or power distribution board where a short between adjacent circuits is a safety risk. Black PBT insulation is standard for this class; it handles the 300 V working voltage without tracking. Six wire entries for three circuits means each pole can accept two wires — useful for daisy-chaining power between blocks without an extra jumper.
Wiring and Termination — Screws and PC Pins
Top termination is a screw clamp — strip the wire, insert into the entry, tighten the steel screw. No crimp tool, no ferrule required, though a ferrule on stranded wire helps keep the strands together under the screw head. The 0.325" pitch means the PC pin spacing matches that center-to-center distance on the board layout. The dual-wall barrier extends above the screw plane, so a screwdriver slipped off the screw head hits the barrier wall, not the adjacent terminal. The zinc clear chromate finish on the screw resists corrosion in humid cabinet environments.
