Circuit breaker size S0 for motor protection, CLASS 10 A release 18...25 A N-release 325 A screw 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 safely isolating the system 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 are naturally suitable 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 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 a quick, maintenance-free, and vibration-resistant connection, and optionally with an integrated auxiliary switch. 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 concept.
