Siemens 3RV2021-1AA10-0DA0 Circuit breaker 1 pc(s) Adjustment range (amperage): 1.1 - 1.6 A

Circuit breaker size S0 for the system protection without phase failure protection A-trip device 1.1...1.6 A N-trip device 21 A Screw connection Standard switching capacity SIRIUS 3RV2 motor starter protectors for system protection for safe shutdown in case of short circuit and protection of the consumers and system against overload, as well as for safe isolation of the system from the mains. The compact and climate-resistant circuit breakers are optimized for use in load feeders thanks to their low waste heat, and of course also for IE3/IE4 motors. Worldwide approvals (e.g. IEC and UL/CSA) and applications in hazardous applications (ATEX or IEC Ex) are self-evident. Devices 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. They are available with screw or spring-type connection for a fast, maintenance-free and vibration-proof connection and optionally with integrated auxiliary switch. The comprehensive accessories, such as auxiliary switch, auxiliary release, alarm switch, etc. are uniform for all sizes. The use of various power supply possibilities, such as the associated SIRIUS 3RV29 infeed system, significantly reduces the main circuit wiring. The 3RV2 motor starter protectors replace the tried and tested 3RV1 series. Simple, efficient, always up-to-date - the SIRIUS modular system.
