Eurostyle 39100 terminal strip, 12 circuits
The Molex 391002312 is the 12-circuit member of the Eurostyle 39100 series — a dual-row enclosed terminal strip rated 40 A per circuit at 300 V. The 0.472" (12.00 mm) pitch gives generous creepage for the voltage rating and enough room to land 8 AWG stranded wire without crowding adjacent terminals. It mounts to a chassis or panel and terminates with top-entry screws against a closed bottom, so the wire is clamped between the screw head and a solid barrier — no feed-through to the back side.
40 A per circuit — sized for power distribution
40 A per circuit means each position carries bus-level current — this block is built for the main power feed, not signal or control wiring. The 8-20 AWG wire range confirms it: 8 AWG is the typical conductor size for a 40 A branch circuit in industrial panel wiring. The dual-row layout gives 24 wire entries (two per circuit), so a single block can serve as a power distribution point with incoming and outgoing wires landed on the same terminal.
Same footprint as the 10-circuit sibling
The 12-circuit 391002312 shares the same 0.472" (12.00 mm) pitch, chassis-mount pattern, and screw-termination style as the 10-circuit 391002310. Both carry the same 40 A, 300 V rating and 8-20 AWG wire range.
