AC-2 at 400 V is 15 kW for slip-ring or wound-rotor motors. AC-4 at 400 V is 29 A for reversing or inching duty where the contactor breaks full stall current. If your application cycles hard, the maximum switching rate at AC-3 is 1,000 operations per hour; at AC-4 it drops to 250 per hour. ## Auxiliary contact capacity The built-in auxiliary contacts handle 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — enough to drive a PLC input or a small relay directly. At 110 V it's 1 A, at 220 V it's 0.3 A. No separate aux block needed for basic feedback. ## Environment and wiring Main circuit terminals are screw-type, accepting 2x (0.75...25 mm²) stranded or 2x (0.5...4 mm²) solid. Side-by-side mounting is allowed with no derating gap — useful when packing contactors tight on a DIN rail.","metaTitle":"Siemens 3RT1034-1AP00-1AA0 SIRIUS Power Contactor, S2, 55 mm","metaDescription":"Siemens SIRIUS 3RT1034-1AP00-1AA0 power contactor, S2 size, 55 mm wide.
