Barrier Strip Selection Note
The Molex Beau 386306403 is a 3-circuit barrier terminal block from the Beau 38630 series, built for panel or through-hole mounting with a flange for secure chassis attachment. It carries a 0.438" (11.12 mm) pitch, rated 25 A per circuit at 600 V, with a dual-wall (2-wall) barrier that isolates adjacent wire entries and increases creepage distance. The top termination uses screws with a zinc clear chromate finish on steel; the bottom terminates as PC pins for soldering into a PCB or wiring to a bus bar.
Position Count and Sibling Fit
This 3-circuit block is the middle position count in the Beau 38630 family, sitting between the 2-circuit 386307802 and the 4-circuit 386307804 at the same 0.438" pitch and 25 A rating. If the BOM calls for 4 circuits, the 386307804 is a drop-in replacement on the same footprint spacing — just one more position in the same barrier style. The 6-circuit 386306606 shares the same pitch and current but comes in tray packaging rather than bulk.
Mounting and Termination Detail
The block accepts 12-24 AWG wire and terminates via top-entry screws with a zinc clear chromate finish. The bottom termination is PC pin.
