For less severe AC-2 duty (slip-ring motors), it's rated at 30 kW at 400 V, and at 500 V it handles 37 kW in standard AC-3 motor starts. Mounting is screw-and-snap-on onto 35 mm or 75 mm standard DIN rail.
Terminal & Wiring Detail
Power circuit accepts solid conductors: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), max 2x (0.75...4 mm²). Stranded connections go up to 2x (10...50 mm²). The control circuit (coil) uses a separate terminal set: 2x (2.5...16 mm²) solid or stranded. These are screw-clamp terminals — strip lengths and torque specs follow standard Siemens SIRIUS practice.
Dimensional Fit
Footprint is 146 mm high by 70 mm wide by 139 mm deep. The 70 mm width allows side-by-side mounting.
Switching Performance & Coil Data
Coil operates at 50 Hz with voltage tolerance 0.8 to 1.1.
Integrated auxiliary contacts (the 1AR00 variant includes one normally-open and one normally-closed) are rated: 10 A at 24 V, 6 A at 230 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 3 A at 400 V. At 690 V the auxiliary is rated 18.6 kW; at 1000 V it's 30 W — these are the switching limits for the control circuit, not the main poles.
