The Siemens 3RV2021-0GA10-0DA0 is a SIRIUS 3RV2 motor starter protector in size S0, configured for system protection without phase failure protection. The A-release is set at 0.45…0.63 A, and the short-circuit release trips at 8.2 A. Termination is via screw terminals, with standard switching capacity.
RoHS compliance is confirmed since October 1, 2009. REACH candidate list information is available on request.
The A-release range of 0.45…0.63 A sets the overload protection threshold for the connected motor — set it to match the motor full-load current (FLC) within that window. The fixed short-circuit release at 8.2 A handles fault clearing independently.
