On a 400 V AC-4 duty cycle it handles 29 A, so this contactor is sized for reversing or jogging applications where the make/break load is heavier than standard AC-3. Side-by-side mounting is permitted — no derating gap needed between contactors on the rail. Accepts solid wire 2x (0.5...1.5 mm²) and 2x (0.75...2.5 mm²), max 2x (0.75...4 mm²); stranded 2x (0.75...25 mm²); and solid/stranded 2x (0.75...16 mm²). At 40 °C the minimum permissible cross-section is 16 mm². Dimensions: 55 mm wide, 112 mm high, 164 mm deep. ## Switching Performance Mechanical life typical 10,000,000 operations. Maximum switching rates: AC-1 1,200 ops/h, AC-2 750 ops/h, AC-3 1,000 ops/h, AC-4 250 ops/h. Arcing time 10...15 ms; AC switching time 7...20 ms. Coil operates at 0.8...1.1 x rated voltage at 50 Hz. ## Environmental Range Operating temperature -25...+60 °C; storage -55...+80 °C.","metaTitle":"3RT1034-1AR04 Siemens SIRIUS Power Contactor, Size S2, 55 mm","metaDescription":"Siemens SIRIUS 3RT1034-1AR04 power contactor, Size S2, screw terminals, 55 mm wide, 164 mm deep. 18.5 kW at 500 V AC-3.
