Side-by-side mounting is supported, allowing dense packing in multi-contactor assemblies. Main power circuit connections use screw-type terminals, accepting stranded conductors up to 2x 25 mm² and solid conductors up to 2x 4 mm². ## Rating Depth and Application Fit The AC-3 rating of 22 kW at 400 V defines the contactor's capability for switching three-phase induction motors under normal running conditions — starting, stopping, and occasional inching. For resistive or lightly inductive loads (AC-1), the contactor's thermal current capacity is not directly stated, but the AC-2 rating of 18.5 kW at 400 V indicates suitability for slip-ring motor starting. The maximum operating rate at AC-3 is 1,000 switching cycles per hour, which aligns with typical conveyor and pump cycling. Auxiliary contact ratings are provided for DC switching: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. These values are critical for control circuit designers sizing pilot devices or PLC outputs feeding the contactor coil. ## Environmental and Compliance Profile No UL or CSA listing is explicitly stated in the available data, but the SIRIUS platform typically carries these approvals; verification against the specific project's certification requirements is recommended before specifying. Dimensions are 112 mm height, 55 mm width, and 115 mm depth, fitting standard 55 mm-wide contactor slots in panel layouts. Wire termination accepts solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and max 2x (0.75 to 4 mm²). Stranded conductors: 2x (0.75 to 25 mm²). This range covers standard motor feeder cables up to 6 mm² for the 22 kW rating, with flexibility for paralleled control wiring.","metaTitle":"Siemens 3RT1035-1AL00 SIRIUS Power Contactor, Size S2, 22 kW","metaDescription":"Siemens SIRIUS 3RT1035-1AL00 power contactor, Size S2, rated 22 kW at 400 V AC-3.
