The Siemens 3RT2016-2AK62-ZW97 is a SIRIUS power contactor in size S00, built for switching motor loads in control panels. The 24 VDC coil with spring-type terminals means no screwdriver needed for the coil wiring — strip, push, done. Rated 10 A at 24 V on the auxiliary contacts, so it handles typical PLC-level signals without a separate interposing relay. Dimensions are 45 mm wide, 70 mm tall, 73 mm deep — fits the standard S00 footprint on 35 mm DIN rail per DIN EN 60715.
Mounting and clearances
Snaps onto 35 mm DIN rail; also accepts screw mounting. Clearance around the contactor: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side. That 6 mm side gap is tight — if you're packing multiple contactors side-by-side, keep that minimum for heat dissipation and arc clearance. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, so panel layout is flexible.
Switching capacity and operating rates
Main contacts rated for AC-1 resistive loads up to 1,000 operations per hour, AC-3 motor switching at 750 ops/h, and AC-4 (plugging/inching) at 250 ops/h. That AC-4 rate is the one to watch — if your application does frequent reversing or jogging, you'll cycle through the mechanical life faster. Mechanical life is listed at 30 million operations typical. Arcing time runs 10 to 15 ms.
Environmental range
Operates from -25 °C to +60 °C; storage range is -55 °C to +80 °C. The storage limit is what governs handling and shipping, not running. If your panel sees ambient above 60 °C, you'll need to derate or move to a larger frame.
Sourcing and lifecycle
Lifecycle stage is listed as current production. This is a standard catalog item in the SIRIUS line. Sourced and quoted to order through independent distribution — availability and current pricing confirmed at quote time against an RFQ.
