Siemens SIEM circuit breaker

Circuit breaker size S0 for motor protection, CLASS 10 A release 1.8...2.5 A N release 33 A spring terminal connection. Standard switching capacity with horizontal auxiliary switch 1S+1Ö. SIRIUS 3RV2 circuit breakers for motor protection ensure safe disconnection in case of short circuits and protect consumers and installations from overload, as well as providing safe isolation of the system from the network. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, and are naturally suitable for IE3/IE4 motors and equally for switching direct current. Global approvals (e.g., IEC and UL/CSA) and applications in explosion-hazardous environments (ATEX or IEC Ex) are standard. Device variants are available for motor protection (also with overload relay function), system protection, short circuit protection of starter combinations, transformer protection, as main and emergency stop switches, and for use in IT networks. They come with screw or spring terminal connections for quick, maintenance-free, and vibration-resistant connections, and optionally with built-in auxiliary switches. The comprehensive accessories, such as auxiliary switches, auxiliary releases, signaling switches, etc., are uniform across all sizes. The use of various energy supply options, such as the associated SIRIUS 3RV29 supply system, significantly reduces the main circuit wiring. The 3RV2 circuit breakers replace the proven 3RV1 series. Simple, efficient, always up-to-date - the SIRIUS system modular kit.
