Barrier Block, 6 Circuits, 0.250" Pitch — 10A at 300V
The Molex 0386106406 is a 6-circuit barrier block from the Beau 38610 series, a screw-termination terminal block family for panel and PCB power distribution. The 0.250" (6.35mm) pitch gives enough spacing to handle the 300V rating without creepage concerns, while the dual-wall barrier design isolates each wire entry. Rated 10A per circuit, this block is sized for control cabinet power feeds, appliance terminal strips, and industrial panel wiring — not signal-level duty.
Flange and Mounting — Panel or PCB
The flange allows the block to be bolted to a panel or chassis, taking the mechanical strain off the through-hole PC pins. This is the difference between a board-mounted terminal strip and one that can serve as a standalone junction point in a cabinet. The through-hole mounting with PC pin bottom termination means the block solders into the PCB and the flange carries the wire-pull load. For a 6-circuit block handling 18-22 AWG stranded wire, the flange is a practical feature — without it, repeated screw torquing can fatigue the solder joints.
Termination and Wire Entry — Screw Clamp
Top termination is screws with a nickel-plated brass screw — standard for field wiring where a screwdriver is the termination tool. The 6 wire entries match the circuit count: one wire per position, clamped under the screw head. The 18-22 AWG range covers the common power and control wiring sizes for this current class. The dual-wall barrier keeps adjacent wires from shorting if a strand strays during termination.
