Circuit breaker size S00 for motor protection, CLASS 10 A release 0.28...0.4 A N release 5.2 A screw connection. Standard switching capacity with horizontal auxiliary switch 1S+1Ö. SIRIUS 3RV1 circuit breaker for motor 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 power supply. 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 and for switching direct current. Worldwide 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, as main and emergency stop switches, and for use in IT networks. They are available with screw connection and optionally with built-in auxiliary switch. The comprehensive accessories, such as auxiliary switches, auxiliary releases, 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. Simple, efficient, always up to date - the SIRIUS system modular concept.
