Each circuit is rated 63 A at 600 V — that's bus-level current, sized for the main feed or a motor branch circuit, not a signal line. Screw top termination with a closed bottom means the wiring lands on the topside and the back is fully insulated — no exposed terminations behind the panel. ## Circuit Counts Across the Series The 391002503 sits at 3 circuits in the Eurostyle 39100 series. Against the 2-circuit 391002502 and the 4-circuit 391002504, the pitch, current rating, voltage, wire range, and mounting stay identical — the only variable is the number of positions and wire entries.","metaTitle":"Molex Eurostyle 391002503 3-Circuit Terminal Strip, 63 A, 600 V","metaDescription":"Molex Eurostyle 39100 391002503 enclosed terminal strip, 3 circuits, 15.00 mm pitch, 63 A, 600 V, 6-14 AWG, screw termination, chassis/panel mount, white PA66 UL94 V-0.
