Circuit breaker size S00 for starter combinations, rated current 2.5 A, N-release 33 A, screw connection. Standard switching capacity of SIRIUS 3RV2 circuit breakers for starter combinations ensures safe protection of consumers against short circuits as well as 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, naturally suitable for IE3/IE4 motors and equally for switching direct current. Global 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), 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-loaded connections for quick, maintenance-free, and vibration-resistant connections, and optionally with built-in auxiliary switches.

The comprehensive accessories, such as auxiliary switches, auxiliary relays, signaling switches, 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 wiring of the main power circuit. The 3RV2 circuit breakers replace the proven 3RV1 series. Simple, efficient, always up to date - the SIRIUS system modular concept.
