Barrier Strip for Panel Wiring — 7 Circuits, 0.438" Pitch
The Molex Beau 38780 387800107 is a 7-circuit barrier strip built for chassis or panel-mounted power distribution. It carries a 0.438" (11.12 mm) pitch between terminals, rated 15 A at 300 V — enough for control cabinet fan trays, small motor starters, or lighting contactor panels where you need a clean screw-terminated junction point. Dual-wall barrier construction (2 Wall) separates each circuit on both sides, reducing the chance of a stray strand bridging across terminals during wiring. The top termination uses screws with a Zinc, Clear Chromate finish; the bottom is closed, so this strip lands on a panel or chassis and the wires enter from one side only. It accepts 14-22 AWG wire across 14 wire entries — two per circuit, which lets you daisy-chain a feed and a load on the same terminal.
Circuit Count vs the 9-Position Sibling
The 7-circuit 387800107 shares the same 0.438" pitch, 15 A rating, 300 V ceiling, and dual-wall chassis-mount format as the 9-circuit 387800109. The difference is the number of positions — 7 here against 9 on the 387800109. If your panel layout has the space and you need an extra pair of circuits for future expansion, the 9-position variant drops into the same mounting pattern per circuit.
The 387800107 is listed as Active on the lifecycle record, so it remains a standard production item. It is ROHS3 Compliant.
