Description
Siemens 3RV20211DA10
circuit breaker frame size S0 for motor protection, CLASS 10 release A 2,2...3,2 A release N 42 A screw terminal standard operating capacity SIRIUS circuit breaker 3RV2 For motor protection for safe disconnection in the event of a short circuit and for overload protection of the loads and the system as well as for the safe separation of the system from the mains.\nThe compact, tropicalized circuit breakers are optimized due to their low heat loss , for use in starters, of course also for IE3/IE4 motors and equally for direct current switching. International approvals (e.g. IEC and UL/CSA) and versions for applications in potentially explosive areas (ATEX or IEC Ex) are obviously available.\nDevice variants for motor protection are available (also with overload relay function ), system protection, short-circuit protection of combined starters, transformer protection. as a main and EMERGENCY STOP switch and for use in IT networks. They are available with screw or spring-loaded terminals for quick, maintenance-free and vibration-resistant connection as well as optionally with a built-in auxiliary switch block.\nAll accessories such as e.g. auxiliary contact blocks, auxiliary releases, signaling contact blocks etc. they are uniformly suitable for all construction sizes. The various power 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 series.\nSimple, efficient, always up-to-date - the SIRIUS modular system.
