The Molex 391002004 is the 4-circuit member of the Eurostyle 39100 series — a 2-row enclosed barrier terminal strip with 0.394" (10.00 mm) pitch, rated 30 A per circuit at 600 V and operating from -40 °C to 105 °C.
Construction and ratings
The PA66 nylon housing carries a UL94 V-0 flammability rating — appropriate for enclosed panel and chassis compartments where the connector may be exposed to adjacent wiring heat loads. Top termination is screw-clamp; the bottom is closed, so no feed-through is available on that face. Zinc-plated steel terminal screws accept 10–18 AWG conductors.
Where it fits
At 10.00 mm pitch and 30 A per circuit, the 391002004 suits panel-level power distribution where multiple branch circuits need a single common-rail bus — the enclosed barrier prevents accidental shorting from loose wire strands in dense wiring trays. The chassis-mount flanges accept standard panel cutouts for the Eurostyle series footprint.
Same series, different position count
The 0391002012 is the 12-circuit member of the same Eurostyle 39100 family — same 0.394" pitch, same 30 A rating, same enclosed-barrier construction. If the panel layout was originally specified around 12 positions and the circuit count can be consolidated to 4, the 391002004 drops into the same mounting footprint without rework. Confirm wire gauge (10–18 AWG) matches the existing harness — both accept the same range.
