The Molex 391002310 is a 10-circuit Eurostyle terminal strip from the 39100 series, arranged in two rows on a 0.472" (12.00 mm) pitch. It's an enclosed-barrier, chassis- or panel-mount block with top screw termination — the kind you'd find in power distribution panels, industrial control cabinets, or equipment where a reliable, field-serviceable interconnect between incoming supply and internal wiring is needed.
Ratings That Matter for the Fit
The 8-20 AWG wire range means you can land a heavy 8 AWG feeder on one side and a smaller control wire on the other, all within the same block. The 0.472" (12.00 mm) pitch gives enough creepage for the 300 V rating without forcing an oversized panel footprint.
Top termination uses steel screws with a zinc finish — the zinc provides corrosion resistance in humid environments while keeping the screw torque consistent across repeated terminations. The bottom termination is closed, meaning the screw terminal is the only wire entry point; there is no through-hole or solder tail on the bottom. Each of the 10 circuits has two wire entries (20 total), so you can daisy-chain or loop wires through adjacent positions. The enclosed barrier physically separates adjacent terminals, reducing the chance of a stray conductor bridging circuits.
