What it is
The Molex Beau 387600105 is a 5-circuit dual-wall barrier strip in the Beau 38760 series, rated 15 A per circuit at 300 V with a 0.375-inch (9.53 mm) pitch across two rows. The top termination uses screw clamps; the bottom is closed. It mounts to the chassis or panel face via flange and accepts 14-22 AWG wire — the 2-wall (dual) barrier construction provides two wire-entry slots per circuit, giving 10 entries total.
What the ratings mean for your fit
The 15 A per-circuit rating puts this squarely in panel-level power distribution duty — lighting bus, motor branch, or control-wiring interconnect. The 14-22 AWG wire range is the governing constraint: at the coarse end (14 AWG) you get the full 15 A; at the fine end (22 AWG) you are limited by the wire ampacity well before the contact does. The dual-wall barrier and 10 wire entries mean each circuit can accept two conductors — useful for daisy-chaining or distributing a single feed to multiple loads without a separate splice. Pitch at 0.375 inch (9.53 mm) defines the mounting hole spacing on the panel cutout — confirm the existing panel layout matches before committing, because the flange mounting holes must align with the circuit pitch. The zinc clear chromate screw finish gives adequate corrosion protection in a typical enclosed panel environment; for outdoor or salt-air exposure the terminal block would need supplementary treatment or a different finish not listed in this variant.
Where barrier strips are used
Barrier strips like the 387600105 are the workhorse of industrial panel wiring — they terminate field wiring from sensors, contactors, and branch circuits onto a single clean bus bar, typically in motor control centres, power distribution panels, and process automation cabinets. The flange mount lets them sit on a panel face or DIN-rail-adapter plate with mechanical retention independent of the wire load. UL94 V-0 thermoplastic housing meets the flammability requirement for enclosed electrical enclosures in most industrial codes.
