It handles 29 A in AC-4 at 400 V, covering the heavy jogging and inching cycles that wear out smaller contactors. The main circuit uses screw-type terminals; the coil operates between 0.8 and 1.1 times its rated voltage at 50 Hz, with a pick-up time of 7 to 20 ms and an arcing time of 10 to 15 ms. ## Duty Ratings and Switching Frequency Maximum switching frequency varies by duty class: 1,200 operations per hour in AC-1 (resistive), 1,000 in AC-3 (normal motor start), 750 in AC-2 (slip-ring motor), and 250 in AC-4 (plugging/inching). Auxiliary contacts are rated 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V, covering typical PLC and relay interface levels. Side-by-side mounting is allowed, so multiple contactors pack tightly in a panel without derating spacing. Dimensions are 112 mm high, 55 mm wide, 115 mm deep — the S2 frame fits standard enclosure cutouts. IP20 on the front, IP00 at the terminals: the connection area needs finger-safe covers if the panel door is open. ## Environmental Range and Wiring The main circuit accepts solid conductors from 2x 0.5 to 1.5 mm² up to 2x 0.75 to 4 mm², and stranded up to 2x 0.75 to 25 mm². Minimum permissible conductor size at 40 °C is 16 mm² — relevant when derating for high ambient. The coil draw at 24 V is 10 A; at 60 V it drops to 2 A, so the control transformer sizing should account for inrush.","metaTitle":"Siemens SIRIUS 3RT1034-1AR00 Power Contactor, Size S2, 415 V","metaDescription":"Siemens SIRIUS 3RT1034-1AR00 power contactor, size S2.
