Circuit breaker size S00 for motor protection, CLASS 10 A-release 9...12 A N-release 156 A 1NO+1NC transverse screw connection standard switching capacity SIRIUS 3RV1 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, and of course also for IE3/IE4 motors. 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, 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 range of accessories, such as auxiliary switches, auxiliary releases, etc. is standard for all sizes. The use of various energy feed options, such as the associated SIRIUS 3RV29 feed system, significantly reduces the main circuit wiring. Simple, efficient, always up-to-date - the SIRIUS modular system.
