Circuit-breaker size S0 for motor protection, CLASS 10 A trip 11...16 A N-trip 208 A spring-cage connection Switching capacity 30 kA at 600 V to UL/CSA SIRIUS 3RV2 circuit-breakers for motor protection for safe disconnection in the event of a short-circuit and protection of the load and system against overload, as well as for safe disconnection of the system from the mains.The compact and climate-resistant circuit-breakers are optimised for use in load feeders due to their low heat dissipation, naturally also for IE3/IE4 motors and equally for switching direct current. Worldwide approvals (e.g. IEC and UL/CSA) and applications in potentially explosive atmospheres (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-cage connection for fast, maintenance-free and vibration-proof connection, and optionally with integrated auxiliary switch.The comprehensive range of accessories, such as auxiliary switches, auxiliary releases, signalling switches, etc., is standardised for all sizes. The use of various energy feed options, such as the associated SIRIUS 3RV29 feed system, significantly reduces the main circuit wiring.3RV2 circuit-breakers replace the tried-and-tested 3RV1 series.Simple, efficient, always up-to-date - the SIRIUS modular system.
