The Siemens SIRIUS 3RT1036-3AP60 is a size S2 power contactor rated for 22 kW at AC-2 duty at 400 V, meaning it handles slip-ring motor loads and reversing applications at that power level. Screw-type terminals on the main circuit accept 2x (0.75... 16 mm²) solid or stranded, with separate control circuit terminals rated for 2x (0.25... 2.5 mm²) solid. Mounts via screw or snap-on onto 35 mm DIN rail per EN 50022, and side-by-side mounting is permitted — no derating gaps required.
Panel footprint is 55 mm wide × 112 mm tall × 115 mm deep — fits standard S2 cutouts. Front face carries IP20 touch protection; the terminal area is IP00, so live parts at the lug connection are exposed — shield with a terminal cover or maintain clearance per IEC 60947-1. Pollution degree 3 rating means it tolerates conductive dust and condensation typical of industrial control panels.
