Circuit breaker size S00 for motor protection, CLASS 10 A release 5.5...8 A N release 10 A 1S+1Ö horizontal screw connection. Standard switching capacity of SIRIUS 3RV1 circuit breakers for motor protection ensures safe disconnection in case of short circuits and protects consumers and installations 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 they 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, as main and emergency-off switches, and for use in IT networks. They come with a screw connection and optionally with a built-in auxiliary switch. The comprehensive accessories, such as auxiliary switches, auxiliary releases, etc., are uniform across all sizes. The use of various power supply options, such as the associated power supply system SIRIUS 3RV29, significantly reduces the main circuit wiring. Simple, efficient, always up-to-date - the SIRIUS system modular concept.
