What it is
The Molex 387200208 is the 8-circuit member of the Beau 38720 series — a 2-wall dual barrier strip rated 15 A per circuit at 300 V, with 0.375-inch (9.53 mm) pitch and screw-top termination. The housing is black thermoplastic, flange-mounted for chassis or panel install, and accepts 14-22 AWG wire. The terminal screws are steel with zinc clear chromate finish; the bottom is closed to prevent debris entry.
What the key ratings mean
The 15 A per-circuit rating is the load ceiling. Barrier strips of this type run their thermal limit through the metal screw and-barrel path — the 14-22 AWG wire gauge range tells you the barrel grips a conductor that is thermally matched to the 15 A rating, not an oversized cable run. 300 V is the dielectric withstand — adequate for the AC mains or DC bus segments this class typically terminates in panel boxes and motor drive housings. The -40 °C to 100 °C operating window covers both cold-start industrial environments and enclosed-panel thermal rise. UL94 V-0 on the housing material means the barrier body is self-extinguishing under flame exposure — relevant for end-product safety certification. The 8 wire entries map one-to-one with the 8 circuits — each circuit is a single-barrel entry point, so the 2-wall dual barrier geometry here differs from the enclosed-barrier variant in other series families.
Where this class is used
Barrier strips of this form factor are the standard field-connect point for AC power distribution, motor starter circuits, and industrial control panels. The flange mounting and closed-bottom geometry suit environments where the strip is surface-mounted to a cabinet back-plate or DIN-rail adapter plate — the flange gives a secondary fastener point that a clip-only mount does not.
Lifecycle and sourcing
Sourced to BOM quantity against RFQ; confirm the flange cutout and panel thickness match your existing assembly before committing.
