The Siemens 3RT1036-3AT60 is a SIRIUS power contactor in size S2, designed for switching motor loads and resistive loads in industrial control panels. It mounts on a 35 mm DIN rail per DIN EN 50022, with screw-type terminals for the main circuit. Rated for 22 kW at AC-2 400 V and 41 A at AC-4 400 V, this contactor handles moderate motor starting and plugging/reversing duties. The AC-2 rating covers wound-rotor motors; AC-4 covers inching or reversing where the contactor makes and breaks full load current. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C. Pollution degree 3 means it tolerates conductive pollution in typical industrial enclosures.
Dimensions are 115 mm depth, 55 mm width, 112 mm height — fits standard S2 contactor footprints. Side-by-side mounting is permitted, saving panel width when multiple contactors are ganged. Terminals accept 2x (0.25…2.5 mm²) solid or 2x (0.75…25 mm²) stranded wire for the main circuit; the auxiliary circuit uses 2x (0.75…16 mm²). IP20 on the front, IP00 at the terminals — enclosure required for terminal protection.
Rated operational voltage is 600 V at 60 Hz. Power ratings include 30 kW at 500 V and 11.4 kW at 690 V, giving flexibility across common industrial voltage levels. Mechanical life is 10 million operating cycles typical. Maximum switching rates vary by duty: 1000 cycles/h at AC-1, 800 at AC-3, 400 at AC-2, 300 at AC-4. Arcing time is 10…15 ms; pick-up/drop-out at AC is 7…20 ms. Substance prohibitance date of 05/01/2012 aligns with RoHS compliance. The contactor carries the SIRIUS brand and is designed for global panel builds.
