Circuit breaker size S0 for motor protection, CLASS 10 A-release 20...25 A N-release 325 A spring-loaded connection Switching capacity 30 kA at 600 V according to UL/CSA SIRIUS 3RV2 circuit breaker for motor protection for safe shutdown in the event of a short circuit and protection of the consumer and system against overload, as well as for safe disconnection of the system from the mains. The compact and climate-resistant circuit breakers are optimized for use in consumer feeders due to their low waste heat, of course also for IE3/IE4 motors and equally for switching direct current. Worldwide approvals (e.g. IEC and UL/CSA) and applications in potentially explosive applications (ATEX or IEC Ex) are a matter of course. , Device variants are available for motor protection (also with overload relay function), system protection, short-circuit protection of starter combinations, transformer protection, as main and EMERGENCY STOP switches and for use in IT networks. They are available with screw or spring-loaded connections for a quick, maintenance-free and vibration-proof connection, and optionally with a built-in auxiliary switch. , The comprehensive range of accessories, such as auxiliary switches, auxiliary releases, signaling switches, etc., is standard for all sizes. The use of various energy feed options, such as the associated SIRIUS 3RV29 feed-in system, significantly reduces the main circuit wiring. , The 3RV2 circuit breakers replace the tried and tested 3RV1 series. , Simple, efficient, always up-to-date - the SIRIUS modular system.
