The Molex 391002106 is the 6-circuit member of the Eurostyle 39100 series — an enclosed-barrier terminal strip built for chassis or panel mounting. It terminates up to 10-18 AWG wire with top-side screws and carries a 30 A per-circuit current rating at 300 V, making it a straight power interconnect for industrial control panels, power distribution boxes, and equipment where you need a fixed wiring point that can handle the current without a PCB.
30 A per circuit is bus-level current — sized for the main power feed or motor branch circuit, not a signal line. The enclosed barrier (shrouded screw terminals) means you can land a screwdriver on the terminal without brushing an adjacent live conductor, which matters when you're working live in a panel. Terminal screws are steel with a zinc finish — the zinc gives corrosion resistance in humid environments; the steel core takes the clamp torque without stripping. Bottom termination is closed, so there is no through-panel access — the strip mounts flush to the chassis or panel face.
The 391002112 is the 12-circuit version at the same 0.394" (10.00 mm) pitch, same 30 A and 300 V ratings, same wire range and housing material. The only decision-relevant difference is position count: 6 circuits here versus 12 on the sibling. If your BOM calls for 12 positions, the 391002112 is the direct match — this 6-circuit part would need two units and a jumper, which adds a panel hole and wiring labour.
