Circuit breaker size S00 for motor protection, CLASS 10 A release 2.2...3.2 A N release 42 A screw connection. Standard switching capacity of SIRIUS 3RV2 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 installation 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 for switching direct current. Global approvals (e.g., IEC and UL/CSA) and applications in explosion-hazardous environments (ATEX or IEC Ex) are standard. Variants are available for motor protection (also with overload relay function), plant 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 quick, maintenance-free, and vibration-resistant connections, 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 power 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 design.
