The 387112206: The 15 A per-circuit rating at 300 V is standard for a 0.375"-pitch barrier block with 14-22 AWG wire capacity — the screw terminal and steel screw with zinc clear chromate finish provide a gas-tight connection that holds up under thermal cycling in a control cabinet. The 0.375" pitch gives enough spacing to land a #6 ring terminal or fork without shorting across adjacent circuits, and the dual-wall barrier adds physical isolation between wires. The 6-circuit count matches the BOM line for a 6-position power distribution point; the flange helps locate the block during assembly and resists torque from the screw terminals.
Against the 3-circuit 387116703 (same 0.375" pitch, 15 A, 300 V, flange, but bottom termination is quick-connect instead of wire-wrap), the 387112206 is the correct choice when the PCB connection requires a wire-wrap post rather than a 0.187" quick-connect tab. The 9-circuit 387106309 from the Beau 38710 series shares the same pitch and ratings but uses PC pin bottom termination and no flange — it is the higher-density option for a flange-less through-hole layout. The 6-circuit 387203206 from the Beau 38720 series matches the circuit count and flange but terminates bottom with solder turrets for chassis-mount applications. Pick the 387112206 when the PCB side needs wire-wrap posts and the panel layout calls for a flange.
