Siemens 3RV2011-0EA10 Circuit Breaker

Siemens 3RV2011-0EA10 is a Sirius motor protector (size S00) that mounts on a DIN rail and provides thermal overload protection for small AC motors in control panels. Operating from 220–690 V AC, it protects motors up to about 0.09 kW with an adjustable overload-trip current of 0.28–0.40 A. The device uses screw-terminals and offers front IP20 protection with finger-safe access, and it arrives without auxiliary contacts. As part of the 3RV2 family, the 3RV2011-0EA10 carries a short-circuit current rating of 65 kA at 480 V, supporting robust protection in typical industrial installations. The Class 10 tripping characteristic ensures fast, predictable response to overloads, making it suitable for protecting small motors in machinery, conveyors, pumps, and fans where space is at a premium due to its compact S00 form factor.
