The Molex Beau 38720 387207515 is a 15-circuit barrier strip with a 0.375" (9.53 mm) pitch, built for through-hole mounting on a PCB. The top termination uses screws with a captive plate, so the clamping force spreads across the full conductor width without loose washers to lose. Wire range is 12-22 AWG.
The 0.375" pitch gives enough creepage for the 300 V rating without forcing an oversized board footprint — you get 15 independent circuits in a row that fits a standard PCB layout. 25 A per circuit means each position carries bus-level current; the limiting factor is the wire gauge and the temperature rise inside the enclosure, not the terminal itself. The dual-wall barrier (2 Wall) between each circuit prevents wire strands from bridging adjacent terminals, which matters when you're landing 12 AWG power conductors in tight quarters.
The 387207515 shares the same 0.375" pitch, 25 A rating, 300 V, and dual-wall barrier construction as the 12-circuit 387207512. If your BOM calls for 15 positions, this is the member; the 12-circuit version won't cover the extra circuits without a second strip.
