The Siemens 3RV2021-1AA10-0DA0 is a SIRIUS 3RV2 motor starter protector — a circuit breaker in size S0, designed for system protection without phase failure protection. Its A-release is set at 1.1...1.6 A, and the short-circuit release trips at 21 A. This is the standard switching capacity variant with screw terminals, so it's a direct fit for panel builds where you need a coordinated motor branch circuit in a compact DIN-rail footprint.
