Siemens Circuit breaker, S2, class 10

Circuit breaker size S2 for motor protection, Class 10 A release 42...52 A N release 741 A screw connection. Standard switching capacity circuit breaker SIRIUS 3RV2 for motor protection to ensure safe disconnection in case of short circuit and to protect consumers and systems from overload, as well as for safe separation of the system from the grid. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, naturally also for IE3/IE4 motors and equally for switching direct current. Worldwide approvals (e.g., IEC and UL/CSA) and applications in explosion hazardous environments (ATEX or IEC Ex) are a matter of course. 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 for all sizes. The use of various energy supply options, such as the associated supply system SIRIUS 3RV29, significantly reduces the main circuit wiring. The circuit breakers 3RV2 replace the proven series 3RV1. Simple, efficient, always up to date - the SIRIUS system modular concept.
