What this is
The Molex 387600302 is the 2-circuit member of the Beau 38760 series — a dual-wall barrier terminal strip rated 15 A per circuit at 300 V. The 0.375 in (9.53 mm) pitch and 2-row layout define its panel footprint; it accepts 14–22 AWG wire at the top via screws with captive plate, and the bottom is closed. Flange-mounting holes on the housing body anchor it to the chassis face before field wiring begins.
Ratings and what they mean for the panel spec
The 15 A per-circuit rating is governed by the wire gauge range (14–22 AWG), not the contact hardware itself — 22 AWG lands at the low end of the accepted range, so a harness spec calling for fine-strand control wire will run the strip well below rating. The dual-wall barrier construction adds mechanical segregation between adjacent circuits; combined with the closed bottom, it reduces the chance of a dropped terminal or wire bridge during field installation on a live chassis rail. Flammability is UL94 V-0 on the thermoplastic housing, and the terminal screws carry a zinc clear-chromate finish on steel — adequate for indoor industrial enclosures, though environments with high humidity or chemical exposure warrant checking the chromate spec against the panel's operating atmosphere.
