The dual-wall means there are two insulating ribs between adjacent circuits, not one — that extra wall reduces the chance of a wire strand bridging to the next terminal in a crowded panel or under vibration. ## Flange Mount and Panel Fit The flange feature on this block lets you bolt it directly to a chassis or panel — the mounting holes are integral to the thermoplastic body, so you don't need a separate bracket. For a field retrofit, that means you can drill a new hole pattern or reuse an existing one without reworking the whole assembly. The bottom termination is closed, so there is no through-hole pin or solder tail — all connections are made at the screw terminals on top.","metaTitle":"Molex Beau 387600303 Barrier Block, 3 Circuit, 0.375\" Pitch","metaDescription":"Molex Beau 387600303 barrier terminal block, 3 circuits, 0.375\" (9.53mm) pitch, 15 A, 300 V, dual-wall, flange mount, black, UL94 V-0.

The pitch, current rating, voltage rating, and flange mount are identical, but the panel cutout and mounting hole spacing scale with circuit count. A panel drilled for the 6-circuit block will have extra mounting positions and a longer opening than the 3-circuit block requires."},{"question":"What compliance documentation is available for 387600303?","answer":"The block is ROHS3 compliant and the insulation carries a UL94 V-0 flammability rating.
