Circuit breaker size S00 for transformer protection A-release 1.4...2 A N-release 42 A screw connection standard switching capacity with transverse auxiliary switch 1S+1Oe SIRIUS 3RV2 circuit breaker for transformer protection for the safe protection of transformers against short circuits and overloads. The compact and climate-resistant circuit breakers are optimized for use in consumer feeders due to their low heat dissipation, 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 system, significantly reduces the main circuit wiring. The 3RV2 circuit breakers replace the proven 3RV1 series. Simple, efficient, always up-to-date - the SIRIUS modular system.
