The Siemens SIRIUS 3RT1516-1AU60 is a Size S00 power contactor with a 24 VDC coil rated at 10 A, designed for screw and snap-on mounting onto 35 mm standard mounting rail per DIN EN 50022. At 24 V rated value the coil draws 10 A, with the contactor switching main circuits up to 230 V at 6 A and 400 V at 3 A. Auxiliary contacts are rated 9 A per NC and per NO contact. The main circuit and auxiliary circuit both carry a rated impulse withstand voltage of 6 kV, placing this contactor in a standard industrial control panel insulation class.
The mounting position allows vertical surface mounting with +/-180° rotation and +/-30° tilt front-to-back, giving flexibility in crowded enclosures. Screw-type terminals on the main current circuit accept solid conductors 2x (0.5... 1.5 mm²) and stranded 2x (0.75... 2.5 mm²), max 2x (0.75... 4 mm²).
Operates from -25 to +60 °C and stores from -55 to +80 °C, with a maximum operating altitude of 2 000 m. Front and terminal protection is IP20. Mechanical life is rated at 30 000 000 cycles typical, with a maximum AC-1 switching frequency of 1 000 1/h.
