What this is
The Molex 387700107 is the 7-circuit member of the Beau 38770 dual-wall barrier strip series, rated 15 A per circuit at 300 V with a 0.375-inch (9.53 mm) pitch. The dual-row 2-wall barrier construction spaces two rows of screw-type top terminations across the strip, accepting 14-22 AWG conductors. Black PBT housing rated UL94 V-0 with zinc-clear-chromate terminal screws mounts directly to the chassis or panel face via the integral flange.
What the ratings mean for your panel layout
The 15 A per circuit rating at 300 V sets the load envelope for power distribution or control wiring in a panel assembly — the dual-wall construction and screw termination are suited to field wiring where conductors need to land and stay under panel vibration. The 14-22 AWG range covers the lighter-gauge signal and control wires common in industrial automation; heavier power runs at this current class typically step up to a larger-gauge barrier strip. The 14 wire-entry count (7 top entries per row) tells you the physical layout density: two entries per circuit means field-side daisy-chaining of a common is practical without adding jumpers.
Where it sits against a peer
The nearest functional peer in the same sourced range is the Molex 0391002012 Eurostyle strip — a 12-circuit, 30 A at 600 V dual-row unit on a 0.394-inch pitch. The 0391002012 carries significantly higher current and voltage headroom but at a wider pitch and greater circuit count; it will not drop into a panel cutout or wiring plan built around the 387700107's 7-circuit, 0.375-inch layout without rewiring. If the load profile genuinely demands 30 A / 600 V, the 0391002012 is the appropriate upgrade path; if you need the exact 7-circuit footprint at this series' pitch, the 387700107 remains the correct BOM line.
