The Siemens Circuit breaker size S0 for system protection without phase failure protection A-release 10...16 A N-release 208 A screw terminal Standard switching capacity Circuit breaker SIRIUS 3RV2 For motor protection for the reliable shutdown in the event of a short-circuit and for protecting the loads and system against overload, and for safe isolation of the system from the network. 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. For Use With Three Phase Motors
