Siemens 3RT1017-1AP01-0AE6 SIRIUS Power Contactor — S00 Frame, Screw Terminals
For AC-4 duty (plugging, inching) at 400 V, the rated operating current is 8.5 A — the figure that governs real reversing or jogging cycles.
Mounting and Terminal Data
Screw-type terminals on the main current circuit accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or a maximum of 2x (0.75 to 4 mm²) solid or stranded conductors. AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. The 72 mm depth leaves clearance behind the DIN rail for wiring ducts or backplane connections. Front protection is IP20; the terminals themselves are also rated IP20.
Environmental Limits and Coordination
This is the spec your panel designer needs for the SCCR calculation.
The instantaneous auxiliary contact (1 N/O) carries 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. At 230 V the rating is 6 A. These are the DC and AC switching limits for the control circuit — verify your PLC output or relay coil draw against these values, especially at higher voltages where the current drops off.
