Beau 38770 barrier block — what it is and where it sits
The Molex 387700104 is the 4-circuit member of the Beau 38770 dual-row barrier strip series, rated 15 A per circuit at 300 V with a 0.375 inch (9.53 mm) pitch. The top termination accepts a flat-blade or Pozidriv driver; the bottom is closed, which limits access to the wire entry face from below the panel face — plan the wire-entry routing before drilling the mounting cutout. The housing is PBT rated UL94 V-0, the terminal screws are steel with zinc clear-chromate plating, and the black colour is standard for this series. It mounts via flange directly to a chassis or panel face.
