3RV23111FC20 SIEMENS large construction size S00 automatic circuit breaker for combined starter nominal current 5 A release N 65 A spring terminal standard operating power SIRIUS 3RV2 Circuit breakers for combined starters for safe protection against short circuits of users and for safe disconnection from the network.\nThe compact and tropicalized circuit breakers are optimized, thanks to their low thermal dissipation, for use in starters, naturally also for IE3/IE4 motors and equally for direct current switching. International approvals are obviously available (e.g. IEC and UL/CSA) and versions for applications in explosion risk areas (ATEX or IEC Ex).\nThere are variants of the device for motor protection (also with overload relay function), system protection, short circuit protection of combined starters, transformer protection. as main switch and EMERGENCY STOP and for use in IT networks. They are available with screw or spring terminals for a quick, maintenance-free connection and resistant to vibrations, as well as optionally with an integrated auxiliary contact block.\nAll accessories such as auxiliary contact blocks, auxiliary releases, signaling contact blocks, etc. are uniformly suitable for all construction sizes. The different energy supply options, such as the SIRIUS 3RV29 power supply system, significantly reduce the wiring of the main circuit.\nThe 3RV2 circuit breakers replace the proven 3RV1 construction series.\nSimple, efficient, always up to date - the SIRIUS modular system.
