The Siemens 3RV2041-4RA10-0DA0 is a SIRIUS-brand circuit breaker designed for system protection — meaning it's the main disconnect and short-circuit protector for a motor branch circuit, not a standalone motor starter. Size S3 frame, so it's the middle of the SIRIUS breaker family, sized for motor loads up to 22 kW at 230 V and rated 84 A in AC-3 duty at 400 V, which is the motor-switching current you'd use for sizing.
At 400 V AC, this breaker interrupts 30 kA. At 240 V AC it handles 100 kA, at 500 V AC it drops to 4 kA, and at 690 V AC to 3 kA. The AC breaking capacities at 400 V and 500 V are higher than the raw interrupting ratings — 65 kA at 400 V and 8 kA at 500 V — which matters if you're using it in a system with a higher prospective fault current and need the AC-rated performance.
