The Molex Beau 38770 387700109 is a 9-circuit barrier block in the Beau 38770 series, designed for chassis or panel-mounted power distribution. It uses a 0.375" (9.53 mm) pitch — a standard spacing that keeps the footprint compact while providing enough creepage for the 300 V rating. Each circuit is rated 15 A, which is typical for a block of this size and wire range (14-22 AWG). The dual-wall (2 Wall) barrier construction reduces the chance of accidental shorts between adjacent terminals during wiring or maintenance.
Top termination is via screws (steel with a zinc, clear chromate finish); the bottom is closed, meaning the screw terminals are the only access point, which suits a dead-end wiring scheme where the block terminates the circuit. The flange feature provides a secure mechanical mount to the panel or chassis using the two mounting holes.
No EOL notice or successor is on record. The base product number is 038770, and the series is Beau 38770 — a well-established barrier block family from Molex. For compliance documentation, the UL94 V-0 flammability rating and RoHS compliance are confirmed in the spec record.
