Siemens SIRIUS 3RT1017-1AP01-1AA0 — S00 Power Contactor, Screw Terminals
The Siemens SIRIUS 3RT1017-1AP01-1AA0 is a size S00 power contactor with screw-type terminals for the main current circuit, rated for switching loads up to 10 A at 24 V DC and 6 A at 230 V AC (50/60 Hz). It mounts via screw and snap-on onto 35 mm standard mounting rail per DIN EN 50022, occupying 45 mm width on the rail, with a depth of 72 mm and height of 57.5 mm. The contactor is rated for an operating temperature range of -25 °C to +60 °C during operation, and its mechanical service life is typical 30,000,000 operating cycles.
Switching Ratings and Motor Duty
For motor switching duty, the contactor is rated at 5.5 kW for AC-2 at 400 V and 8.5 A for AC-4 at 400 V — these are the values that govern real motor starting and reversing applications, not the resistive-load numbers. The DC switching ratings are specified per voltage: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. For AC switching at 50/60 Hz, the contactor handles 6 A at 230 V, 3 A at 400 V, and 0.8 to 1.1 times the rated value depending on frequency.
Termination and Coordination
Screw terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and up to 2x (0.75 to 4 mm²) for the main circuit, with AWG equivalents of 2x (20–16), 2x (18–14), and 1x 12. For Type 2 coordination (no weld), the required upstream fuse is gL/gG 20 A; for Type 1 coordination, a 35 A gL/gG fuse is specified. Side-by-side mounting is permitted, with a minimum 6 mm clearance to adjacent devices on the side.
