What This Barrier Block Does in the Assembly
The Molex Beau 38760 0387600102 is a 2-circuit barrier terminal block with 0.375" (9.53 mm) pitch, designed for chassis or panel mounting where a screw-clamp wire termination is needed. The 2-wall (dual) barrier between each circuit keeps wire strands separated and prevents accidental shorts during termination — a practical detail when you are landing 14-22 AWG field wiring. The flange at each end lets you bolt the block to a panel or enclosure wall, so the screw torque goes into the chassis, not into a PCB or plastic housing. The screw terminals use a steel screw with zinc/clear chromate finish; the bottom is closed, meaning the screw does not pass through the block, so the termination is captive on the wire side only.
Sizing the Wire and the Torque
The 14-22 AWG wire range covers most power and signal field wiring. The 15 A rating is per circuit at the screw terminal — at 14 AWG the wire itself can carry that current, but the screw clamp is the limiting junction, so the connection should be torqued to the manufacturer's spec (not listed here, but standard for this class). The 0.375" pitch gives enough room for a standard screwdriver tip and the wire bend radius; you are not fighting adjacent terminals the way you would on a 0.200" pitch block.
The block mounts to a chassis or panel through the flange holes — no DIN rail adapter, so plan for screw-mounting. The top termination is screw-clamp; the bottom is closed, meaning the block has no through-hole pins for a PCB. Two rows of wire entries (4 total) let you land two wires per circuit if needed, though the 2-circuit count means two independent circuits, each with two entry positions. The black thermoplastic body carries the UL94 V-0 rating.
