What this is
The 387112206: Rated 15A per circuit at 300V, it covers the wire range of 14-22 AWG — a span that captures the conductors common in industrial control panels, power distribution blocks, and motor-starter harness segments. The housing is black PBT rated for -40°C to 100°C, and the flange feature provides a dedicated fastening point on the panel face or chassis rail — the series is panel-mount by design rather than DIN-rail footed. Terminal screws are steel with a zinc clear-chromate finish; the dual-wall (2-wall) barrier construction increases creepage distance between adjacent circuits compared to a single-wall open-strip design.
What it does
Barrier blocks of this type sit at the panel boundary — field conductors land on the top screws while the wire-wrap tails connect to a PCB or pass through to a secondary circuit layer. The 6-circuit count suits compact junction points or single-load-branch distribution in equipment that predates modular DIN-rail terminal blocks. The flange enables panel-face mounting with a screw-through boss, keeping the connector stationary under vibration better than a loose clip-in DIN-rail foot in high-shock environments. Six wire entries (one per circuit) with top-screw clamping means each conductor is independently terminated and individually extractable — useful in maintenance scenarios where a single branch must be isolated without disturbing the others.
