Product description

The Siemens SIRIUS 3RV1021-0AA10 is a motor protection circuit breaker in size S0, designed for safeguarding electric motors against overloads and short circuits. It features a thermal overload release with a setting range of 0.11 to 0.16 A and a short-circuit release set at 2.1 A. This breaker is rated for Class 10 overload protection and utilizes standard screw terminals for connection.

This specific model is a phased-out product, with the SIRIUS 3RV2 series being its successor, and the 3RV2011-0AA10 being the preferred replacement type. It is suitable for direct-on-line motor starting applications where reliable protection is essential for motor longevity and operational safety.
