Product details

The Siemens SIRIUS 3RT1034-1AR04 is a Size S2 power contactor with screw-type terminals on the main current circuit, built for 50 Hz nominal frequency and rated for AC-3 motor switching at 18.5 kW at 500 V and 10 kW at 690 V. 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.
