The coil holds at 24 VAC nominal, with an operating range of 0.8 to 1.1 times rated voltage at 50 Hz. ## Mounting and termination — DIN-rail snap-on, screw terminals The S2 frame occupies 55 mm width, 112 mm height, and 164 mm depth — measure the enclosure depth before committing; that 164 mm projection can interfere with gland plates in shallow 200 mm cabinets. Main circuit terminals are screw-type, accepting solid conductors from 2x 0.5 to 4 mm² and stranded up to 2x 25 mm². The minimum permissible cross-section at 40 °C is 16 mm² — sized for the full thermal current without derating in a warm panel. Pollution degree 3 (conductive pollution) means the contactor is suited for industrial enclosures where some condensation or dust is expected. ## Switching capacity and motor duty At 500 V, the contactor switches 30 kW; at 690 V, 11.4 kW — the voltage derating reflects the arcing constraints at higher potentials. Maximum switching frequency varies by duty: 1000 cycles/hour at AC-1 resistive, 800 at AC-3 (standard squirrel-cage starting), 400 at AC-2, and 300 at AC-4. For a high-cycle application like a stamping press with frequent reversals, the AC-4 limit of 300 cycles/hour is the binding constraint. DC switching capacity is also specified: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. If you are switching DC brake coils or solenoid valves, use these figures — the AC ratings do not carry over. The lifecycle stage is current. The part carries a substance prohibitance date of 05/01/2012, aligning with RoHS compliance.","metaTitle":"Siemens 3RT1036-1AB04 SIRIUS Power Contactor, S2, 24 VAC","metaDescription":"Siemens 3RT1036-1AB04 SIRIUS power contactor, S2 frame, 24 VAC 50 Hz coil.
