Terminal Block Overview
The Molex Eurostyle 393570003 is a 3-position, single-level terminal block from the Eurostyle 39357 series, designed for printed circuit board mounting with a horizontal wire entry orientation. It uses a screw-rising cage clamp termination — the screw tightens a clamp that pulls the wire against a current bar — rated for 12 A at 300 V. Accepts 16-28 AWG wire, making it a fit for control panel wiring, power supplies, and industrial I/O modules where field termination and re-termination are routine.
The 12 A per-circuit rating is the headline power limit. The 300 V rating is line-to-line. The 0.31 Nm torque spec on the M3 screw is not optional.
