Eurostyle 39100 Terminal Strip — 4-Circuit Power Distribution Block
The Molex 391002304 is a 4-circuit member of the Eurostyle 39100 series of enclosed terminal strips. It is a chassis- or panel-mount power distribution block with a 0.472" (12.00mm) pitch, rated 40 A at 300 V. The white PA66 housing carries the UL94 V-0 flammability rating, and the top screw termination accepts 8-20 AWG wire. This is a straightforward power interconnect for industrial control panels, power supplies, and equipment where a compact, high-current terminal strip is needed.
The 40 A per-circuit rating is the headline — this is a power block, not a signal strip. Each screw terminal can carry a full branch circuit, and the 0.472" (12.00mm) pitch provides the creepage needed for the 300 V rating without forcing an oversized footprint. The enclosed barrier type means the live metal is shielded on both sides, reducing the risk of accidental contact during wiring. The 8-20 AWG wire range covers most power and distribution wiring; the steel screw with zinc finish provides corrosion resistance in panel environments. The PA66 insulation holds up to typical industrial thermal cycling without embrittlement.
There is no last-time-buy window or official successor on record.
