What this contactor delivers
The Siemens SIRIUS 3RT1467-2XJ46-0LA2 is a size S10 contactor rated for 156 A at 480 V and 144 A at 600 V — those are the AC-1 thermal current figures that govern resistive and lightly inductive loads. At 400 V it carries 3 A for DC switching (DC-1 duty). Screw fixing, so it bolts to a backplate or panel rather than snapping onto a rail — plan for that in the enclosure layout.
Dimensions: 210 mm high, 145 mm wide, 202 mm deep. Clearance: 10 mm upwards, 20 mm forwards, 10 mm sideways, 10 mm downwards — tight but workable in a standard 600 mm deep enclosure. Wire range accepts 2x (0.5...1.5 mm²) solid or stranded, 2x (0.75...2.5 mm²), and max 2x (0.75...4 mm²). Single 11 mm mounting hole.
