The resistive load rating (AC-12) is 10 A maximum, so it handles heater banks or lighting circuits within that limit. DC switching capability is specified at several voltages: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — useful for DC motor brakes or solenoid loads in mixed-voltage panels. The S00 footprint is compact at 45 mm wide, 57.5 mm high, and 72 mm deep — fits standard 45 mm-wide DIN-rail slots. Wire range for main terminals accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) — solid or stranded. AWG equivalents are 2x (20 to 16), 2x (18 to 14), or 1x 12. The enclosure is rated IP20 on the front and at the terminals, so it is intended for installation inside a panel with a higher-rated enclosure. ## Environmental and protection coordination Type 1 coordination (contactor may need replacement after fault) allows a 35 A gL/gG fuse. This lets the panel designer choose between tighter protection or higher fault tolerance.","metaTitle":"Siemens 3RT1017-1AU61 SIRIUS Power Contactor, S00, 3NO, 8.5A","metaDescription":"Siemens 3RT1017-1AU61 SIRIUS power contactor, size S00, 3-pole NO, 8.5 A AC-4 at 400 V, 5.5 kW AC-2/AC-3.
