What it is and what it does
The Siemens SIRIUS 3RT2016-1DG47 is a power contactor in size S00, designed for switching motor loads and resistive loads in industrial control panels. It mounts via screw and snap-on onto a 35 mm DIN rail per DIN EN 60715, fitting a standard panel layout. Rated for a 125 V DC coil, it picks up at 80% of rated voltage and drops out at 110% of rated voltage, ensuring reliable operation with a standard DC control supply. The coil uses screw-type terminals for wiring. DC switching capacity is 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V. For AC loads at 400 V, it switches 3 A. At 230 V AC, it handles 1 hp motor loads. The main contact range is rated 20 to 12 A. Mechanical service life is 30 million operations typical. Switching frequency varies by duty: 1000 cycles/h at AC-1, 750 cycles/h at AC-2, AC-3, and AC-3e, and 250 cycles/h at AC-4. Arcing time is 10 to 15 ms; DC operating time is 7 to 13 ms.
Panel integration and wiring
Dimensions are 45 mm width, 58 mm height, and 117 mm depth, fitting a compact S00 footprint. Minimum clearances: 10 mm upwards, downwards, and forwards; 6 mm at the side. Mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward/backward. Terminals accept solid or stranded conductors from 0.5 to 4 mm². For multi-conductor termination, it accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². No auxiliary switch is included on this variant. Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C, covering most indoor industrial environments.
