The Siemens 3RT6015-1AN22 is a SIRIUS Size S00 power contactor with a 24 VDC coil drawing 6 A on the auxiliary contact at 24 V. The AC-3 motor-switching voltage ceiling is 690 V, and at 400 V 60 °C it handles a 10.5 kW motor load — enough for a moderate pump or conveyor drive.
Screw-type terminals on the main circuit accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded.
Switching frequency and duty class
The maximum mechanical switching rate is 10 000 cycles per hour, but the electrical limit depends on duty: AC-1 (resistive) max 1 000 cycles/h, AC-3 (motor) max 750 cycles/h, AC-4 (inching/plugging) max 250 cycles/h. For high-cycle applications like rapid indexing, stay within the AC-3e limit of 750 cycles/h to avoid contact welding.
