Product Introduction
The Molex 391002104 is a 4-circuit member of the Eurostyle 39100 series terminal strip family. It is a dual-row, enclosed-barrier terminal block designed for chassis or panel mounting, with top-entry screw termination and a closed bottom. The 0.394" (10.00mm) pitch gives generous spacing between terminals for 10-18 AWG wire, and the white polyamide (PA66) insulation carries a UL94 V-0 flammability rating for equipment inside an enclosure. Typical applications include power distribution, industrial control panels, and field-wired junction boxes where a compact, high-current terminal strip is needed.
The 30 A per circuit rating suits bus-level current. The 300 V rating is typical for industrial control voltage.
How It Compares: 4 vs 12 Circuits
The 4-circuit 391002104 shares the same 10.00 mm pitch, 30 A rating, dual-row layout, and white color as the 12-circuit 391002112. The decision is purely position count: 4 circuits suit a small branch distribution point, while the 12-circuit version handles a larger panel. Both use the same wire gauge range (10-18 AWG), same enclosed barrier, and same chassis/panel mounting pattern.
