Product details

Terminal Strip, Three Circuits, Screw Termination

The Molex Eurostyle 39100 391001903 is a 3-circuit enclosed terminal strip on 0.315" (8.00mm) pitch, rated 20 A at 300 V. It accepts 12-22 AWG wire through screw top termination with a closed bottom — the wire enters from the top and terminates against the screw clamp; the closed bottom means no through-panel access, so wiring is entirely front-side. The white UL94 V-0 polyamide (PA66) housing mounts to a chassis or panel, and the dual-row layout gives 6 wire entries (two per circuit). This is the 3-circuit member of the Eurostyle 39100 series, a common choice for power distribution and control wiring in industrial enclosures, lighting panels, and HVAC equipment where a compact, serviceable barrier strip is needed.

The housing material is rated UL94 V-0.

Frequently asked questions

What is the wire range for 391001903?

The 391001903 accepts 12-22 AWG wire, covering solid and stranded copper for power and signal connections.

Will 391001903 drop into a panel specified for 391001904?

Yes, both use the same 0.315" (8.00mm) pitch, same mounting, same ratings — the only difference is 3 circuits vs 4 circuits. If your panel has space for the longer 4-circuit block, the 3-circuit fits the same mounting pattern but leaves one position empty.

What compliance documentation is available for 391001903?

The 391001903 is ROHS3 compliant and the housing carries a UL94 V-0 flammability rating. Compliance documentation is available upon request with an RFQ.

Where can I buy 391001903 and how is it quoted?

The 391001903 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for your target quantity.
