Ambient temperature range for operation is -25 to +60 °C. ## Motor Load Ratings and Coordination For AC-4 duty at 400 V, the rated operational current is 8.5 A. These are the figures that govern motor switching capability — the AC-1 resistive rating is higher, but for induction motor loads, AC-2/AC-4 is the relevant curve. With type of coordination 2 required, the upstream protection is a gL/gG fuse rated 20 A. For type 1 coordination, the fuse rating is 35 A. This determines the short-circuit protection the contactor can withstand without welding its contacts. Auxiliary contact ratings: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 0.3 A at 220 V — these are the switching capacities for the control circuit, not the main power path. ## Mounting and Enclosure Integration The 45 mm width, 60 mm height, and 114 mm depth fit the standard S00 footprint. Side-by-side mounting is permitted, so multiple contactors can be ganged without spacing gaps. IP20 on the front and at the terminals — suitable for installation inside a closed control panel where no washdown or dust ingress protection is required at the device level. Substance prohibitance date of 01.07.2006 aligns with RoHS compliance.","metaTitle":"Siemens 3RT1017-2CB04 SIRIUS Power Contactor, S00, 24 VDC Co","metaDescription":"Siemens 3RT1017-2CB04 SIRIUS power contactor, size S00. 24 VDC coil, spring-loaded terminals, screw/snap-on 35mm DIN rail.
