Rated for 50/60 Hz operation with an operating range of 0.8... 1.1 times the rated voltage, this contactor handles a 22 kW motor at 500 V and 11.4 kW at 690 V. The AC-3 switching frequency maxes out at 1,000 operations per hour, while AC-4 duty (plugging/reversing) is rated at 300 ops/h. Mechanical life is a typical 10,000,000 operations, so it holds up in high-cycle applications like conveyors or pump stations. The AC-1 maximum rating of 1,200 operations per hour covers purely resistive loads like heaters, where contact wear is minimal. AC-3 at 1,000 ops/h is the standard for starting and stopping squirrel-cage motors under load — the rating that matters for most conveyor, fan, and pump duty. The auxiliary contact ratings at various voltages tell you what the built-in auxiliary can switch: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V DC. For DC switching, the arcing time of 10... 15 ms and the AC operating time of 7... 20 ms matter for coordinating with PLC scan cycles or safety relay timing. The S2 frame measures 55 mm wide, 112 mm high, and 115 mm deep — check your enclosure depth before committing. Screw terminals on the main circuit accept solid conductors: 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), max. 2x (0.75... 4 mm²). Stranded conductors: 2x (0.75... 25 mm²). For mixed solid/stranded runs, 2x (0.75... 16 mm²). This range covers standard motor feeder cables from 1.5 mm² up to 25 mm² for the main power path.","metaTitle":"Siemens 3RT1035-1AK60 SIRIUS Power Contactor, S2, 22 kW at 5","metaDescription":"Siemens 3RT1035-1AK60 SIRIUS power contactor, size S2, rated 22 kW at 500 V.
