The Siemens 3RT7016-1AP01 is a SIRIUS size S00 contactor with three main poles, a 230 V AC 50/60 Hz coil, and screw-type terminals for both main and control circuits. It's rated for AC-3 switching up to 690 V, with a 400 V AC-3 rating of 6 A and a 690 V AC-3 rating of 1 A — so it handles motor loads up to about 3 kW at 400 V three-phase, typical for small conveyors, pumps, or fans in a control panel. The coil draws 0.8 W on closing and holds at 0.27 W DC, which keeps the heat load low inside a crowded enclosure. Surge voltage resistance is rated at 6 kV, matching the insulation coordination for a 690 V insulated system (pollution degree 3).
Operating temperature range is -10 to +55 °C, storage from -25 to +70 °C.
Switching performance and protection
Maximum switching frequency is 750 operations per hour under AC-3 duty (motor starting), and 250 ops/h under AC-4 (plugging/reversing). Shock resistance is 9.8g at 5 ms and 5.9g at 10 ms sine pulse — robust enough for most industrial machinery but not rated for continuous vibration environments like crushers or shakers without additional damping.
