What it is
The Beau 387303108 is an 8-circuit barrier strip from the Beau 38730 series — a single-row 2-wall (dual-barrier) terminal block designed for panel and chassis-level wiring. Pitch is 0.438" (11.12 mm) per circuit, and the top termination uses direct-drive screws that accept wire from above while the bottom side terminates to an insulated solder turret for PCB attachment. Rated 15 A per circuit at 300 V, the block accepts 14–22 AWG solid or stranded conductors. The housing is PBT/polyester, rated for continuous operation from -40 °C to 110 °C.
Sourcing and lifecycle
Listed Active with ROHS3 Compliant status — no official successor or cross-reference on record for the 387303108. Quoted to order against the BOM quantity. Confirm the circuit count and pitch match the existing panel position before committing; sourcing is per RFQ.
Wire and termination match
The 14–22 AWG window is sized for the lighter end of industrial power wiring — fine for signal distribution, control circuits, and low-amp branch connections. The dual-barrier profile provides a physical guard between adjacent live conductors, which is the point of the 2-wall design on this series. The zinc/clear chromate screw finish on the steel screw gives basic corrosion resistance on the termination side — appropriate for enclosed panel environments but not for direct weather exposure without additional sealing.
