Siemens 3RV2021-4EA20-0BA0 Circuit breaker 1 pc(s) Adjustment range (amperage): 27 - 32 A

Special type of motor circuit breaker size S0 for motor protection, CLASS 10 A trip unit 27...32 A N trip unit 400 A spring connection Standard switching capacity Ambient temperature -50 °C 500 switching cycles SIRIUS 3RV2 motor protection motor starter for safe shutdown in the event of short circuit and protection of consumers and plant 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 by their low waste heat, of course also for IE3/IE4 motors and equally for switching DC current. Worldwide approvals (e.g. IEC and UL/CSA) and applications in explosion-prone applications (ATEX and/or IEC Ex) are obvious.Devices versions are available for motor protection (also with overload relay function), system 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 a screw or spring-type connection for a fast, maintenance-free and vibration-proof connection and optionally with integrated auxiliary switch.The extensive accessories, such as auxiliary switch, auxiliary release, signaling switch etc. Is uniform for all scales. The use of various power supply options, 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.
