Siemens Leistungsschalter

Circuit breaker size S0 for system protection without phase failure protection. A-trigger 23...28 A, N-trigger 364 A, screw connection. Standard switching capacity of SIRIUS 3RV2 circuit breakers for system protection to safely disconnect in case of short circuits and to protect consumers and systems from overload, as well as to safely isolate 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 of course suitable for IE3/IE4 motors. Worldwide approvals, such as IEC and UL/CSA, and applications in explosion-prone environments 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-loaded connections for quick, maintenance-free, and vibration-resistant connections, and optionally with an integrated auxiliary switch. The comprehensive accessories, such as auxiliary switches, auxiliary triggers, signaling switches, etc., are uniform for all sizes. The use of various energy supply options significantly reduces the main circuit wiring. The 3RV2 circuit breakers replace the proven series 3RV1. Simple, efficient, always up to date - the SIRIUS system modular system.
