What it is
The Molex 391002008 is the 8-circuit member of the Eurostyle 39100 enclosed barrier terminal strip series. It runs 0.394 inch (10.00 mm) pitch across two rows of four positions, rated 30 A per circuit at 600 V, with screw-top closed-bottom termination accepting 10-18 AWG wire into 16 individual wire entries.
Ratings that drive the fit
The 30 A per circuit rating at 600 V places this squarely in medium-power panel distribution — industrial automation, HVAC controls, motor branch circuits. The enclosed barrier housing means live terminals are shrouded on three sides, which is the safety architecture that makes barrier strips the go-to for field wiring panels where a gloved hand or loose tool might stray across adjacent poles. Wire gauge range 10-18 AWG covers the full span from power feeder down to control signaling conductors. The dual-row layout with 16 individual wire entries means four wire entries per circuit — enough for daisy-chain jumpers without crowding the termination. PA66 insulation carries a UL94 V-0 flammability rating across an operating range of -40°C to 105°C — wide enough for both cold-storage environments and enclosed panels that run warm. Zinc-plated steel terminal screws provide the clamping force needed for long-term vibration resistance at the panel. The closed bottom on each barrier prevents异物 ingress and satisfies the enclosed construction requirement for certain panel certifications.
Where it sits against its siblings
The 391002008 at 8 circuits shares the same 0.394 inch pitch, 30 A, 600 V, and enclosed dual-row construction as the 0391002012, which carries 12 circuits instead. If your panel cutout and DIN rail footprint were specced around the 12-position strip, the 8-position member will physically drop in — same pitch, same current, same mounting footprint — but you'll have four fewer positions wired. The reverse (dropping a 12-position into an 8-position BOM) requires a rewire of the circuit count.
