Top termination uses steel screws with a zinc clear-chromate finish — corrosion-resistant for industrial cabinet environments. The bottom termination is closed, meaning the screw terminals are only accessible from the top, which suits panel-mount installations where the back of the block is against the chassis. The integrated flange provides a fixed mounting hole pattern for secure bolting to the panel. The 387800112 sits at 12 circuits in the Beau 38780 family. If the BOM calls for a different position count, the same 0.438\" pitch, 15A rating, and chassis-mount footprint carry across siblings: the 387800109 (9 circuits), 387800114 (14 circuits), and 387800116 (16 circuits) share the identical form factor and termination — only the number of wire entries changes. No rewiring of the panel layout is needed if you stay within the series; the mounting hole spacing scales with the circuit count.","metaTitle":"Molex Beau 387800112 Barrier Block, 12 Circuits, 0.438\" Pitch","metaDescription":"Molex Beau 38780 barrier block, 387800112, 12 circuits, 0.438\" (11.12mm) pitch, 15A, 300V, chassis/panel mount, top-screw termination, UL94 V-0, RoHS3.
