The same contactor also carries an 18.5 kW rating at 400 V AC-2 (for slip-ring motors or mixed loads) and a 35 A rating at 400 V AC-4 (for reversing or inching duty where the contactor opens under full load). The S2 footprint is 55 mm wide by 112 mm high by 164 mm deep — a compact envelope for a contactor rated to 22 kW. ## Terminals and wiring Solid wire accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²). Stranded wire handles 2x (0.75 to 25 mm²). Solid or stranded combined accepts 2x (0.75 to 16 mm²). At 40 °C the minimum permissible conductor cross-section is 16 mm². These ranges cover most panel wiring up to the contactor's full rated current. ## Switching performance and endurance Rated frequency is 50 Hz, with an operating range of 0.8 to 1.1 times nominal. Maximum mechanical switching rates: 1,200 operations per hour at AC-1, 600 at AC-2, 1,000 at AC-3, and 300 at AC-4. Typical mechanical endurance is 10 million operations. Auxiliary contact ratings: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, 3 A at 400 V.","metaTitle":"Siemens 3RT1035-1AD04-1AA0 SIRIUS Power Contactor, 22 kW at","metaDescription":"Siemens SIRIUS 3RT1035-1AD04-1AA0 power contactor, S2 size, 22 kW at 500 V AC-3.
