SIRIUS S00 power contactor — 24 VDC coil, screw terminals
The Siemens 3RT2016-1AK61-ZW96 is a SIRIUS S00 power contactor with a 24 VDC magnet coil terminated via screw-type terminals. It snaps onto 35 mm DIN rail per DIN EN 60715 or screws directly to a mounting plate, occupying 45 mm of panel width. The auxiliary switch is built in, with contacts rated for switching loads at voltages from 24 V (10 A) up to 440 V (0.2 A), covering typical control-circuit and signal-level applications.
Duty-cycle limits and thermal envelope
Maximum switching frequency depends on the load category: 1 000 operations per hour under AC-1 resistive loads, 750/h under AC-2 or AC-3 motor duty, and 250/h under the severe AC-4 plugging/reversing cycle. The contactor is rated for operation from -25 °C to +60 °C ambient and can be stored between -55 °C and +80 °C. Mounting position is flexible — the unit can be rotated ±180° on a vertical surface or tilted ±22.5° forward/backward, which helps when fitting into tight enclosures.
Wiring and clearance
Screw terminals accept solid or stranded wire from 0.5 mm² up to 4 mm², with dual-wire capacity for 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or 2x 4 mm². Minimum clearance around the contactor: 10 mm above, below, and forward; 6 mm at the sides. Overall dimensions are 58 mm high, 45 mm wide, and 73 mm deep — the S00 frame size keeps it compact for high-density panel layouts.
