What the ratings mean for the job
The 387206212: The 15 A per-circuit rating is the limiting figure for this part — it is a panel power distribution block, not a high-current bus bar, so 15 A circuits are appropriate for branch wiring at the panel level. Wire gauge range of 14-22 AWG covers the standard panel harness run; going finer than 22 AWG risks insufficient clamp bite, while 14 AWG maxes the current capacity the screw termination can safely carry. The housing is black PBT rated UL94 V-0, meaning it self-extinguishes and is safe for confined panel enclosures where incabinet temperature can approach 100 °C at the connector surface.
Lifecycle and sourcing posture
The 387206212 is Active and ROHS3 Compliant — no lifecycle watch flags are present on this part. Quoted to order against BOM quantity; confirm the exact panel cutout dimensions against the series drawing before committing to a new design slot. The matching mating hardware (wire-side clamping bar, optional cover strip) should be verified from the Beau 38720 series datasheet to complete the assembly specification.
