Barrier Strip for Panel and Board-Level Power Distribution
The Molex Beau 38630 386307804 is a 4-circuit barrier strip with a 0.438" (11.12 mm) pitch, built for through-hole PC-pin termination on one side and screw-with-captive-plate field wiring on the other. It's the sort of terminal block you spec when you need a clean, serviceable power distribution point on a PCB — each of the 4 circuits carries 25 A at 600 V, and the dual-wall (2 Wall) barrier between positions keeps adjacent terminals physically isolated so a stray screwdriver or loose strand doesn't bridge the line. The black PBT insulation is rated for the full temperature envelope of the 25 A load, and the steel screws with zinc clear chromate finish resist corrosion in industrial cabinet air. Wire range is 12-24 AWG on the top side, terminated by tightening the captive-plate screw — the plate clamps the conductor without damaging strands, which is the difference between a reliable termination and a field failure six months in. Bottom side is a PC pin that solders into the board, so the whole assembly is one rigid unit once populated.
What 25 A and 600 V Mean for Your Layout
The 0.438" pitch provides creepage distance for that voltage rating. Wire range 12-24 AWG covers panel wiring for 25 A duty.
Active Production — No Obsolescence Headache
The 386307802 is the 2-circuit version of the exact same barrier strip — same 0.438" pitch, same 25 A / 600 V rating, same screw-with-captive-plate top termination and PC-pin bottom. The only difference is circuit count: 4 positions here versus 2 on the sibling. If your BOM calls for 4 circuits, this is the one; if you need fewer, the 386307802 drops into the same board footprint pattern but shorter. No rewiring or panel modification needed to swap between them — just match the position count to your circuit count.
