What it is — Beau 38770 series, 2-circuit barrier block
The Molex 387700202 is a 2-circuit, dual-wall barrier strip in the Beau 38770 series, designed for chassis and panel wiring in industrial automation and power distribution applications. Pitch is 0.375" (9.53 mm) with a 2-row layout and screw-top termination accepting 14-22 AWG conductors — 4 wire entries across the 2 circuits means each circuit can land two conductors at the termination point.
Housing and mounting — panel fit
The black PBT housing carries a UL94 V-0 flammability rating, which is the minimum acceptable for enclosed industrial panels — it does not support combustion and self-extinguishes. The flange feature on the body provides a registered mounting face against the chassis panel surface, preventing rotation under cable load. Bottom termination is closed, so no live circuit is exposed at the underside of the block.
