What This Terminal Strip Is
The Molex Eurostyle 391001906 is a 6-circuit, dual-row terminal strip from the Eurostyle 39100 series. It uses a screw-top, closed-bottom termination — each circuit gets a zinc-plated steel screw that clamps the wire against a current bar, and the closed bottom means no exposed conductor on the underside. The 0.315" (8.00 mm) pitch gives enough spacing for 12 AWG wire and the 300 V rating, making it a straightforward choice for panel wiring where you need a fixed, serviceable power distribution point.
The 12-22 AWG wire range covers the common panel conductors from a 12 AWG feeder down to a 22 AWG control wire, all clamped under the same screw.
Mounts to a chassis or panel — the closed bottom means no through-hole PCB footprint. The dual-row layout gives 12 wire entries.
The 391001906 sits between the 5-circuit 391001905 and the 7-circuit 391001907 at the same 0.315" (8.00 mm) pitch, same 20 A / 300 V rating, same screw-top / closed-bottom construction. The only difference is the circuit count and the number of wire entries — 10 for the 5-circuit, 12 for this 6-circuit, 14 for the 7-circuit. If your BOM calls for exactly 6 circuits, this is the one; if you need 7, the 391001907 drops into the same panel footprint with one more terminal position.
