Eurostyle 39100 Terminal Strip — 2 Circuits, 20 A at 300 V
The Molex 0391001902 is a 2-circuit Eurostyle terminal strip from the 39100 series, designed for fixed panel or chassis mounting in industrial control and power distribution applications. It carries a 20 A per circuit current rating at 300 V, supported by the 8.00 mm pitch that provides the creepage and clearance needed for branch-circuit power levels. The block accepts 12-22 AWG wire and terminates via screws on the top, with a closed bottom that prevents debris ingress and provides a clean panel-side appearance.
Wire Range and Termination — 12-22 AWG, Screw Clamp
The 0391001902 accepts 12-22 AWG wire, covering both heavier power conductors and smaller control wiring in a single block. Top termination uses steel screws with a zinc finish; the screw clamp captures the conductor against the current bar. The block has 4 wire entries for 2 circuits, meaning each circuit can terminate two wires — useful for daisy-chaining power or signal without a separate jumper. The closed bottom keeps the panel-side wiring area clean and prevents accidental shorting to the mounting surface.
This terminal block is designed for chassis or panel mounting — it screws or bolts to a flat surface, not a DIN rail. The PA66 insulation material provides mechanical strength and electrical isolation at temperature extremes.
