It is a dual-row terminal block with 12 wire entries, designed for chassis or panel mounting where a secure, screw-terminated power distribution point is needed. The dual-wall barrier construction separates adjacent terminals to reduce the risk of accidental shorts between circuits. Rated 15A at 300V, this block handles moderate power levels typical of industrial control panels, HVAC equipment, and lighting distribution. The 14-22 AWG wire range covers the common field-wiring sizes for these applications. A flange on each end provides a mounting point for screw-down to a panel or chassis. The closed bottom means the screw terminals are not accessible from the underside — the block is intended for top-entry wiring only. ## Construction and Field Wiring The screw finish, combined with the captive plate, gives consistent clamping force on stranded or solid wire in the 14-22 AWG range. The closed bottom means the screw depth is fixed; the wire is inserted from the top and clamped by the plate. This is a standard barrier-block layout — no special tooling beyond a screwdriver is needed for termination. The 2-row, 12-wire-entry arrangement means each of the 6 circuits has two wire positions — one per row — allowing daisy-chaining or dual-feed per circuit. The 0.375\" pitch provides enough spacing between adjacent terminals for the 300V rating without forcing a tight layout on the panel. The Beau 38770 series is a long-running Molex line, so the tooling and supply base are established.","metaTitle":"Molex Beau 38770 0387700306 Barrier Block, 6 Circuit, 0.375\"","metaDescription":"Molex 0387700306 Beau 38770 barrier strip, 6 circuits, 0.375\" pitch, 15A, 300V, screws with captive plate, UL94 V-0.
