What it is and where it fits
The Siemens 3RT2016-1DM47 is a SIRIUS power contactor in the compact Size S00 frame, designed for switching motor loads in control panels. It mounts on a 35 mm DIN rail per EN 60715, with screw and snap-on fastening, and accepts solid or stranded wire from 0.5 to 4 mm² at the screw-type terminals. The 24 VDC coil pulls in at 0.8 of rated voltage and drops out reliably; the DC operating time is 7 to 13 ms, with an arcing time of 10 to 15 ms. The contactor is rated for AC-3 motor switching at up to 750 operations per hour, and AC-4 inching duty at 250 ops/h — so for a conveyor or pump start/stop, it handles the duty cycle comfortably, but frequent plugging or reversing will need the lower AC-4 rate.
Mounting and integration
The contactor occupies a 45 mm wide DIN-rail footprint, 58 mm tall, 117 mm deep. It can be mounted in any orientation on a vertical surface, including ±180° rotation and ±22.5° tilt forward or backward. Clearance to adjacent components: 10 mm upward, 10 mm forward, 10 mm downward, 6 mm at the sides. The screw terminals accept two conductors per clamp — 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded.
Switching capacity and ratings
The main contacts are rated for AC-1 resistive loads at up to 1000 ops/h, AC-2 and AC-3 motor loads at 750 ops/h, and AC-4 at 250 ops/h. For DC switching, the contactor is rated at 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. The auxiliary switch configuration is 20...12 (normally open / normally closed). Ambient operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C.
