Circuit breaker size S2 for starter combinations, rated current 59 A, N-trigger 845 A, screw connection, increased switching capacity. SIRIUS 3RV2 circuit breakers for starter combinations provide safe protection for consumers in case of short circuits and ensure safe disconnection from the power supply. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, and they are naturally suitable for IE3/IE4 motors as well as for switching direct current. Worldwide approvals and applications in explosion-hazardous environments are a given. Device variants are available for motor protection, plant 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-loaded connections for quick, maintenance-free, and vibration-resistant connections, and are optionally available with built-in auxiliary switches. The comprehensive accessories, such as auxiliary switches, auxiliary triggers, signaling switches, etc., are uniform across 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 concept.
