Siemens Circuit breaker 1 pc 3RV2411-1HA20

Circuit breaker size S00 for transformer protection A-release 5.5...8 A N-release 163 A spring terminal connection standard switching capacity circuit breakers SIRIUS 3RV2 for transformer protection to ensure safe protection of transformers against short circuits and overloads. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, naturally also for IE3/IE4 motors and equally for switching direct current. Global approvals (e.g., IEC and UL/CSA) and applications in explosion-hazardous environments (ATEX or IEC Ex) are standard. Variants are available for motor protection (also with overload relay function), plant protection, short-circuit protection of starter combinations, transformer protection, as main and emergency stop switches, and for use in IT networks. They come with screw or spring terminal 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, signaling switches, etc., are uniform across all sizes. The use of various power supply options, such as the associated power supply system SIRIUS 3RV29, 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 kit.
