The Siemens SIRIUS 3RT2016-2AP01-ZW97 is a size S00 power contactor with a 24 VDC coil and spring-type terminals. It's rated for AC-3 switching at up to 750 operating cycles per hour, which covers the typical motor-start duty for pumps, fans, and small conveyors in a control panel. The 45 mm wide footprint and screw/snap-on mounting to a 35 mm DIN rail (per DIN EN 60715) mean it slots into a standard panel layout without special bracketing.
Mounting position is hanging on a horizontal surface, with clearance requirements of 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side for arc dissipation and airflow. The spring-type terminals accept solid or stranded wire from 0.5 to 4 mm² (2x per clamp), so no ferrule crimping is required for stranded conductors — strip and insert. Operating temperature range is -25 to +60 °C; storage range extends from -55 to +80 °C.
