The Molex 387600104 is a 4-circuit dual-row barrier block in the Beau 38760 series, operating at 15 A per circuit with a 300 V rating across a 0.375" (9.53 mm) pitch body. The black UL94 V-0 thermoplastic housing carries a flange for chassis or panel mounting, and the top termination accepts screws while the bottom is closed — an enclosed base that protects the wire entry zone from debris in industrial cabinet environments.
Wire interface and termination
The 387600104 accommodates 14–22 AWG conductors through 8 wire entries — two per circuit — with screw clamping at the top. The zinc clear-chromate terminal screws drive into a steel screw barrel, which holds the conductor against the brass-over-nickel terminal post. For field maintenance the screw-head accepts a standard flat blade; the closed bottom prevents debris ingress into the wire cavity between mounting cycles.
Where barrier blocks like this land
Beau 38760 barrier blocks sit in machine-tool control cabinets, industrial HVAC panels, and process-control back-planes — anywhere a harness assembler needs a visible, screw-clamped bus point that a technician can trace with a multimeter probe without fishing through a connector body. The dual-wall barrier construction isolates each circuit pair to reduce accidental shorting during live working, and the flange mounting tolerates panel cutout tolerance without the block pulling through the sheet metal.
