Siemens 3RV2021-0FA10 Circuit breaker 1 pc(s) Adjustment range (amperage): 0.35 - 0.5 A

Circuit breaker size S0 for motor protection, CLASS 10 A trip unit 0.35...0.5 A N trip unit 6.5 A screw connection Standard switching capacity SIRIUS 3RV2 motor protection for safe shutdown in the case of short circuit and protection of 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, of course also for IE3/IE4 motors and for switching DC current equally. Worldwide approvals (e.g. IEC and UL/CSA) and applications in explosion-prone applications (ATEX and/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 for example Auxiliary switch, auxiliary release, alarm switch, etc. is 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.
