Panel-Mount Barrier Block for Power Distribution
The Molex 0387700112 is a 12-circuit barrier strip from the Beau 38770 series, designed for chassis or panel mounting where a screw-terminated power distribution point is needed. The 0.375" (9.53mm) pitch spaces the 24 wire entries (two rows of 12) across a block that bolts down via its integral flanges — no PCB footprint required.
What the 15 A and 300 V Ratings Mean for the Installation
The 300 V rating sets the maximum working voltage between adjacent circuits or to ground; the 0.375" pitch and dual-wall barrier provide the creepage distance for that voltage class in a clean, dry environment. The 14-22 AWG wire range means the block accepts solid or stranded conductors from a 14 AWG power feed down to a 22 AWG control signal, all under the same screw clamp.
Mounting and Termination — Flanged Chassis Fit
The flanges on each end of the block accept a mounting screw (not included — order separately) to secure the block to a panel or chassis. The top termination uses captive screws that clamp the wire against a current-carrying plate; the bottom termination is closed, meaning the block is a feed-through or dead-end point, not a pass-through to a second set of terminals. The steel screws with zinc, clear chromate finish resist corrosion in a cabinet environment. The dual-row layout gives 24 wire entries in a 12-circuit block — two wires per circuit position, one per row, sharing the same terminal plate.
