Barrier Block, 9 Circuits, 0.375" Pitch
The Molex Beau 38720 387203209 is a 9-circuit barrier terminal block with a 0.375" (9.53mm) pitch, rated 15A at 300V. It uses a dual-wall (2 Wall) barrier design with screw top termination and an insulated solder turret bottom. The black thermoplastic housing includes a flange for chassis or panel mounting, and accepts 14-22 AWG wire. This is the 9-circuit member of the Beau 38720 series, sharing the same pitch, current rating, and construction as the 8-circuit 387203208 and 6-circuit 387203206 siblings.
The 0.375" (9.53mm) pitch gives you enough terminal spacing for 14-22 AWG wire with a screw clamp — the wire entries are spaced wide enough that adjacent conductors don't short under vibration or when the screw is tightened. The dual-wall barrier between terminals adds creepage distance, which is what lets this block hold 300V in a 0.375" pitch without tracking.
9 Circuits vs 8 — Same Footprint, One More Terminal
The 387203209 carries 9 circuits at the same 0.375" (9.53mm) pitch as the 8-circuit 387203208. The block length increases by one pitch increment — about 0.375" — so the panel cutout and mounting hole pattern shift by that amount. The terminal screw finish (zinc, clear chromate) and steel screw material are identical across the series. If your BOM calls for 8 circuits and you have a 387203208 on hand, the 387203209 won't drop into the same panel without moving the mounting holes. If you need 9 circuits, this is the one.
