Operating temperature range is -25 to +60 °C, storage -55 to +80 °C, and pollution degree 3 suits industrial environments with conductive contamination. The AC-3 motor-switching rating at 400 V is 22 kW, corresponding to a 41 A make/break capability in AC-4 duty at the same voltage. For resistive loads (AC-1), the contactor can cycle at up to 1000 operations per hour; AC-3 duty maxes at 800 ops/h, AC-4 at 300 ops/h. These figures define the thermal and mechanical limits for repetitive starting and inching applications. DC switching ratings are provided per voltage step: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. Screw terminals accept solid conductors 2x (0.25 to 2.5 mm²) and stranded conductors 2x (0.75 to 25 mm²) on the main circuit. The minimum permissible cross-section at 40 °C is 16 mm² for the main circuit — ensure the panel wiring matches this for full rated current. The S2 frame size is a common Siemens platform, so auxiliary contact blocks and surge suppressors from the SIRIUS family fit without adapters.","metaTitle":"Siemens 3RT1036-3BB44-3MA0 SIRIUS Power Contactor, S2, 24 VD","metaDescription":"Siemens 3RT1036-3BB44-3MA0 SIRIUS power contactor, size S2, 24 VDC coil, screw terminals, IP20 front, current production.
