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.","metaTitle":"Molex Beau 386306403 Barrier Strip, 3 Circuits, 25 A, 600 V","metaDescription":"Molex Beau 38630 barrier terminal block, 386306403, 3 circuits, 0.438\" pitch, 25 A, 600 V, dual-wall, flange mount, black.
