The Molex Eurostyle 39100 391002012 is a 12-circuit terminal strip built for panel-mounted power distribution. It uses a dual-row layout on a 0.394" (10.00mm) pitch, giving you 24 wire entries in a compact footprint — each circuit gets its own screw clamp on top, with a closed bottom that keeps conductors contained inside the enclosed polyamide barrier. Rated 30 A at 600 V, it handles the kind of bus-level current you'd route through a control cabinet or industrial panel, and the 10-18 AWG wire range covers the heavy-gauge stuff without needing an adapter.
The 30 A per-circuit rating is the headline number, but it's the 600 V isolation and the 0.394" (10.00mm) pitch that let you run that current without worrying about creepage between adjacent terminals. The enclosed barrier — UL94 V-0 polyamide — contains any arc or flash within the strip, which matters when the panel gets a hard short. The zinc-plated steel screws hold torque without galling, and the closed bottom means you terminate from the top only — no access underneath, so plan your wire routing accordingly.
The 391002009 is the 9-circuit version of this same strip — same 0.394" (10.00mm) pitch, same 30 A / 600 V rating, same white polyamide housing, same chassis/panel mount with top screw termination. The only difference is the circuit count: 12 positions here versus 9 on the 391002009, which changes the overall length of the strip. No rewiring trick will make a 9-circuit strip cover a 12-circuit requirement — match the position count to the circuit count.
