What the 387068008 Is
The Molex 387068008 is the 4-circuit member of the Beau 38706 dual-row barrier strip family. It presents 8 individual wire-entry positions across two rows, terminates on 0.325 inch (8.26 mm) pitch, and is rated 20 A per circuit at 300 V — suited for power distribution and control wiring inside industrial enclosures, motor-start circuits, and lighting panels where a accessible, high-current terminations point is needed.
Pitch, Mounting, and Termination
The 0.325 inch (8.26 mm) pitch with through-hole mounting and a screw-top / PC-pin-bottom configuration places this strip into panel-mount or PCB-edge termination roles. The dual 2-wall barrier construction contains each conductor in its own channel, reducing the chance of a field-technician cross-wire on adjacent circuits — a meaningful reliability detail in high-vibration machinery. Screw-head entry on top accepts 12-22 AWG conductors; the bottom PC pins drop into a plated through-hole footprint on the PCB for a secondary mechanical anchor and electrical through-connection.
Ratings That Drive the Selection
The 300 V rating covers the voltage for the terminal block's 20 A per circuit ceiling. Wire gauge down to 12 AWG means the block itself, not the wire, is the current-limiting element at the upper end of the range.
Material and Finish
The PBT housing provides good dielectric strength and moderate chemical resistance for indoor industrial environments. Zinc clear chromate on the terminal screws adds corrosion resistance at the clamping interface, and steel screw material gives the torque margin needed to cold-form a reliable crimp onto a 12 AWG conductor without thread stripping under repeated field service. The black housing colour differentiates this barrier block from the white-bodied Eurostyle series in the same brand — useful when a technician is visually sorting spares at the storeroom shelf.
