3RV2011-0GA20 Siemens SIRIUS 3RV2 Motor Protection Circuit Breaker, 0.45–0.63 A
The Siemens 3RV2011-0GA20 is a SIRIUS 3RV2 circuit breaker in size S00, designed for motor protection with CLASS 10 tripping. Siemens describes it as having an overload (A) release adjustable from 0.45 to 0.63 A, an instantaneous short-circuit (N) release at 8.2 A, spring-type terminals and standard switching capacity. In one compact 45 mm unit it protects small motors against overload and short circuit and gives safe isolation from the supply. It is also Siemens’ preferred successor to the phased-out 3RV1011-0GA20.

Key Benefits of the SIRIUS 3RV2
- Complete motor protection: thermal overload and magnetic short-circuit protection in one device
- 100 kA breaking capacity: short-circuit proof up to 690 V AC at this rating
- Spring-type terminals: quick, maintenance-free and vibration-resistant wiring
- Low power loss: Siemens optimised the compact 3RV2 for consumer feeders with low waste heat, including IE3/IE4 motors
- Phase failure sensitivity: responds to phase loss
- Expandable: can be fitted with auxiliary switches and other SIRIUS 3RV2 accessories
- Reduced wiring: compatible with the SIRIUS 3RV29 infeed system
- Clear status indication: switching position shown by the rotary handle
Replacement for 3RV1011-0GA20
Siemens lists the 3RV1011-0GA20 as a phased-out product, with the 3RV2011-0GA20 as its preferred SIRIUS 3RV2 successor. Siemens notes that the overall depth of the 3RV2011 is greater than that of the previous 3RV1011, so check the panel’s available depth when upgrading.
