Circuit breaker size S0 for motor protection, Class 10 A release 27...32 A N release 400 A screw connection. Standard switching capacity of SIRIUS 3RV2 circuit breakers for motor protection to safely disconnect in case of short circuit and to protect consumers and installations from overload, as well as to safely isolate the system from the grid. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, naturally also suitable for IE3/IE4 motors and equally for switching direct current. Worldwide approvals and applications in explosion-hazardous environments are a given. Device variants are available for motor protection (also with overload relay function), system 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 releases, and signaling switches, are uniform across all sizes. The use of various energy supply options significantly reduces the main circuit wiring. The 3RV2 circuit breakers replace the proven series 3RV1. Simple, efficient, always up-to-date - the SIRIUS system modular concept.
