Siemens Circuit breaker

Circuit breaker size S0 for system protection without phase failure protection. A-trigger 0.14...0.2 A, N-trigger 2.6 A, screw connection. Standard switching capacity of SIRIUS 3RV2 circuit breakers for system protection ensures safe disconnection in case of short circuits and protects consumers and systems from overload, as well as providing safe isolation 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, and are naturally suitable for IE3/IE4 motors. Global approvals (e.g., IEC and UL/CSA) and applications in explosion-prone environments (ATEX or IEC Ex) are standard. Device variants are available for motor protection (also with overload relay function), system protection, short-circuit protection for starter combinations, transformer protection, as main and emergency stop switches, and for use in IT networks. They come with screw or spring terminals for quick, maintenance-free, and vibration-resistant connections, and are optionally available with an integrated auxiliary switch. The comprehensive accessories, such as auxiliary switches, auxiliary triggers, signaling switches, etc., are standardized across all sizes. The use of various energy supply options, such as the corresponding 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 concept.
