What it is
The Molex 393570004 is the 4-circuit member of the Eurostyle 39357 series — a side-entry through-hole terminal block built around a 0.138" (3.50 mm) pitch and a screw-rising cage clamp termination that grips the full conductor cross-section without cold flow. Rated 12 A per circuit at 300 V with a wire range of 16-28 AWG, the clamp saddle and M3 screw are nickel-plated copper alloy while the contact interface is tin-plated. Operating range spans -40 °C to 105 °C in a black PA/Nylon housing that survives the thermal and mechanical demands of industrial panel wiring.
