The Siemens SIRIUS 3RT1017-1AF01-ZX95 is a Size S00 power contactor rated for motor switching at 5.5 kW on both 500 V and 690 V supplies, and carries 10 A at 24 V in AC-12 duty for resistive loads.
Coordination and terminal data for panel integration
Screw-type terminals on the main circuit accept solid conductors up to 2x 4 mm² (or 2x 0.5–1.5 mm² fine-stranded), with AWG equivalents of 2x 20–16 and 1x 12 for the main contacts. For Type 2 coordination (no-weld after fault) the required upstream fuse is 20 A gL/gG; Type 1 coordination allows a 35 A gL/gG fuse, which lets the contactor be replaced after a short-circuit event. Front face carries IP20 finger protection; side clearance of 6 mm is needed only when mounting against non-insulated surfaces — zero clearance when side-by-side with another SIRIUS contactor.
