What it is
The Molex 387600306 is the 6-circuit member of the Beau 38760 dual-wall barrier block family. It runs at 0.375 inch (9.53 mm) pitch across two rows, rated 15 A per circuit at 300 V, with a black thermoplastic housing and a panel-mount flange for through-hole or chassis attachment.
Top termination and wire fit
Top termination uses screws with a captive plate — the plate holds the wire barrel flat against the bus bar so that torque applied to the screw goes into the clamp, not into the wire slipping sideways. It accepts 14-22 AWG solid or stranded conductors across 12 wire entries (two per circuit), which covers the mid-gauge range common in industrial control panels.
Flame rating and industrial use
The housing carries a UL94 V-0 flammability rating, the highest classification in the UL94 test standard. Barrier blocks of this type are used as dead-front terminal strips in control cabinets, panel feeds, and distribution boards where a shrouded screw termination beats a hand-soldered connection for field serviceability.
Lifecycle and sourcing
Listed as Active and ROHS3 Compliant — sourced to order against BOM quantity. Confirm circuit count and flange hole pattern against the existing panel cutout before placing the order.
The bottom termination is closed, so no live bus is exposed below the block — which is the expected configuration for panel-mounted barrier strips where the mounting surface must not contact live conductors. The terminal screw finish is zinc with clear chromate, which provides corrosion resistance on the hardware without affecting the wire-side clamping surface.
