What the 386306606 is
The Molex 386306606 is the 6-circuit member of the Beau 38630 series barrier block family — a single-row, dual-wall strip with top screw termination and a through-hole PC pin at the bottom for PCB mount. At 0.438" (11.12 mm) pitch it sits in the mid-range of the Beau 38630 geometry, and its 25 A per circuit at 600 V rating puts it squarely into industrial power-distribution territory rather than signal-level duty. The block accepts 12-24 AWG conductors at the screw clamps — the zinc clear chromate hardware on the terminal screws handles the torque without galling, and the six discrete wire entries align one-per-circuit so each termination is isolated under the dual-wall barrier wall. The black PBT housing holds dielectric integrity across the rated temperature range.
What the key ratings mean for selection
The 25 A per circuit rating is the load ceiling — not a total bus figure, so a 6-circuit block can carry 25 A through each independent pair of screws. The 600 V rating covers most AC and DC panel-level distribution rails up to that voltage. The two ratings together determine the application scope: this is a power-termination block, not a signal interconnect. Pitch at 0.438" (11.12 mm) governs the board footprint and the panel cutout — the through-hole PC pin pattern at the bottom aligns with the pitch for standard PCB routing. Match the pitch to the existing board land pattern before specifying. The 12-24 AWG wire gauge range is wide enough to handle both heavier harness runs and smaller control conductors on the same strip — a useful flexibility in panel builds where mixed gauge is common. The screw clamp accepts the conductor without a ferrule on solid wire and grips reliably on stranded with standard torque.
Where this class of connector is used
Barrier strips like the 386306606 are the traditional panel-entry point for AC mains and DC bus conductors in industrial enclosures, motor controls, and power supplies. The dual-wall barrier provides the creepage distance needed at higher voltages, and the through-hole PC pin version routes the circuit cleanly into a PCB where the downstream conversion or control logic lives. Field technicians favor the screw termination because it requires no special tooling — a standard screwdriver is all that is needed to land or replace a conductor on the bench or in the field.
Lifecycle and compliance
The 386306606 carries an Active product status and ROHS3 Compliant designation. For procurement against a BOM line, the confirmed Active status means it is quotable to order in standard production quantities without a last-time-buy watch. ROHS3 covers the substance-restriction requirements for most EU industrial and commercial equipment builds.
