Mounts via screw and snap-on onto 35 mm DIN rail per EN 50022, with ±180° rotation possible on a vertical surface and ±22.5° tilt forward/backward — useful when you need to orient the panel wiring for access. Dimensions are 112 mm high, 55 mm wide, 115 mm deep — the S2 frame size is a common footprint in Siemens SIRIUS contactor families, so panel cutouts and busbar layouts often carry over. ## Termination and environment Main and auxiliary/control circuits use screw-type terminals; the main terminals accept 2x (0.75…16 mm²) solid/stranded or 2x (18…2 AWG). Rated for pollution degree 3 (industrial environment with conductive or dry non-conductive pollution), operating from -25 to +60 °C, and storage from -55 to +80 °C. Coil draws 6 A at 24 V AC 50/60 Hz, 1 A at 110 V, 0.3 A at 220 V, and 6 A at 230 V — the 24 V coil current matters for control transformer sizing and fuse selection. Substance prohibitance date of 03/01/2017 aligns with RoHS/REACH compliance timelines; the product extension for auxiliary switches indicates modular add-on capability.","metaTitle":"Siemens 3RT5036-1AC20 SIRIUS Power Contactor, 38 kW at 400 V","metaDescription":"Siemens 3RT5036-1AC20 SIRIUS S2 power contactor, 38 kW at 400 V 60°C, 690 V insulation, screw terminals, snap-on DIN rail.
