The 24 VDC coil draws 10 A at 24 V rated value, and the contactor handles motor loads up to 4.5 kW at 400 V AC-3 (the standard three-phase motor duty) and 5.5 kW at 690 V. For DC switching, it's rated 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — useful for switching DC solenoids or smaller DC motors in the same panel.
The closest peer is the 3RT1016-1AR11, which shares the same Size S00 frame and 24 VDC coil voltage but uses a different coil terminal arrangement (screw vs. spring-cage). Both mount on the same DIN rail footprint and have the same AC-3 motor ratings. The deciding factor is whether your panel is wired for screw terminals (1AK22) or prefers spring-cage terminals (1AR11) — the 1AR11 uses the 2AP02 spring-cage variant's terminal style. They are not drop-in interchangeable without checking the coil wiring interface.
The part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.
As a SIRIUS contactor, it carries CE marking for the European market and is designed to meet IEC/EN 60947-4-1 for contactors and motor starters. RoHS and REACH compliance declarations are available from Siemens on request. The part is not individually UL-listed but the SIRIUS family carries UL/CSA recognition under the relevant component program.
