The Siemens SIRIUS 3RT1034-1AG60-1AA0 is a power contactor in the S2 frame size, rated for motor switching at 18.5 kW at 500 V AC-3 and 10 kW at 690 V AC-3. The coil is rated for 50/60 Hz, 100 V at 50 Hz and 100–110 V at 60 Hz. Mechanical life is 10 million operations typical; maximum operating rate is 1000 cycles per hour under AC-3 duty, 250 under AC-4. The front carries IP20 protection; the terminals are IP00. Pollution degree 3 rated, so it tolerates conductive dust in industrial enclosures.
Main circuit terminals are screw-type, accepting solid conductors 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), max 2x (0.75–4 mm²), and stranded 2x (0.75–25 mm²). Overall dimensions: 55 mm wide, 112 mm high, 115 mm deep — fits a standard 55 mm DIN slot.
