Terminal Strip for Panel Wiring — 9 Circuits, Dual-Row
The Molex Eurostyle 391001809 is a 9-circuit enclosed barrier terminal strip from the Eurostyle 39100 series, designed for chassis or panel-mount power distribution. It carries 20 A per circuit at 600 V across a 0.315" (8.00 mm) pitch — the generous spacing gives enough creepage for the voltage rating without forcing an oversized panel footprint. The dual-row layout packs 18 wire entries into the 9-circuit footprint, so each position accepts an incoming and an outgoing wire under the same screw clamp. Top termination uses steel screws with a zinc finish, and the bottom is closed — no through-panel studs or solder tails. The white PA66 housing carries a UL94 V-0 flammability rating and covers a -40°C to 105°C operating range, suiting it for industrial control cabinets, HVAC panels, and power distribution boxes where the terminal strip lives inside an enclosure.
Position Count vs Siblings in the 39100 Series
The 391001809 sits between the 8-circuit 391001808 and the 10-circuit 391001810 at the same 0.315" (8.00 mm) pitch, same 20 A / 600 V rating, same white PA66 V-0 housing. The only difference is the circuit count — 9 positions against 8 or 10 — which changes the overall strip length and the number of wire entries (18 vs 16 or 20).
Wire termination is top-entry screw clamp, accepting 12-22 AWG. The terminal screw is steel with a zinc finish. The bottom termination is closed — no bottom-side access, so the strip mounts directly to a panel or chassis surface. Each of the 9 circuits has two wire entries (one per row), giving 18 total wire positions. The enclosed barrier type provides physical isolation between adjacent terminals, reducing the risk of accidental shorting during wiring or service.
