The Molex 0386306404 is a 4-circuit barrier block from the Beau 38630 series, designed for screw-clamp termination of 12-24 AWG wire. It carries a 25A per circuit current rating at 600V, making it suited for industrial control panels, power distribution junctions, and motor branch circuits where a permanent, field-serviceable connection is required. The dual-wall barrier between terminals provides physical isolation that reduces the chance of accidental shorts during wiring or maintenance.
This block accepts chassis, panel, or through-hole PCB mounting — the integral flange lets you bolt it to a panel or enclosure wall, which transfers the screw torque away from the solder joints. Top termination is via steel screws with zinc clear chromate finish; bottom termination uses PC pins that solder into a PCB. The 0.438" (11.12mm) pitch gives generous spacing for 12 AWG wire and screwdriver access, unlike tighter-pitch blocks that crowd adjacent terminals.
