The Siemens SIRIUS 3RV2 Circuit breaker size S00 for the reliable protection of transformers against short-circuit and overload. Thanks to their low heat loss, the compact and climate-resistant circuit breakers are optimized for use in load feeders, and also for IE3/IE4 motors, of course, and equally for the switching of direct current. Worldwide approvals (e.g. IEC and UL/CSA) and applications in hazardous areas (ATEX or IEC Ex) are a matter of course. Device versions are available for motor protection (also with overload relay function), plant protection, short-circuit protection of starter combinations, transformer protection, as main and EMERGENCY OFF switches and for use in IT networks. The 3RV2 motor starter protectors replace the well-proven 3RV1 series. The use of different energy infeed options, such as the associated SIRIUS 3RV29 infeed system, considerably reduces the main circuit wiring.
