Integrator note — what the ratings mean for fit
The Siemens SIRIUS 3RT2016-1TP02-0RA0 is a Size S00 power contactor with a 24 VDC coil, screw-type terminals, and an integrated auxiliary switch. It snaps onto 35 mm DIN rail per DIN EN 60715, so it lands in any standard control-panel profile without adapter plates. The 45 mm width and 73 mm depth leave room alongside motor starters and overload relays in a typical S00 footprint. The auxiliary contact is rated across a wide voltage range: 10 A at 24 V, 3 A at 400 V, and 0.2 A at 440 V — meaning it handles both low-voltage PLC signals and higher-voltage interlocking without a separate interface relay. That saves a DIN slot and a wiring step. Mechanical endurance is 3 000 000 cycles typical, and the maximum switching frequency hits 1 000 1/h under AC-1 (resistive load), 750 1/h under AC-3 (motor load), and 250 1/h under AC-4 (plugging/inching). For a motor starter duty, AC-3 at 750 operations per hour covers most conveyor and pump cycles without derating.
Mounting and wiring constraints
Fastening is screw and snap-on onto 35 mm DIN rail. The mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward/backward, so it fits tight enclosures where the rail is angled. Side clearance to adjacent devices is 6 mm; forward/upward/downward clearance is 10 mm — standard for S00 contactors. Wire range: solid or stranded 0.5 … 4 mm², or two conductors per terminal (2x 0.5 … 1.5 mm², 2x 0.75 … 2.5 mm², or 2x 4 mm²). Main contact torque range is 20 … 12. Operating temperature is -25 … +60 °C; storage temperature is -55 … +80 °C. That covers most indoor panel environments and unheated warehouses.
