Siemens Circuit-breaker Transformer 9-12.5A 3RV2411-1KA

Circuit breaker size S00 for transformer protection A-release 9...12.5 A N-release 260 A screw connection. Standard switching capacity circuit breakers SIRIUS 3RV2 for transformer protection to safely protect transformers against short circuits and overload. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, and are of course suitable for IE3/IE4 motors as well as for switching direct current. Worldwide 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-loaded connections for quick, maintenance-free, and vibration-resistant connections, and optionally with an integrated auxiliary switch. 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 corresponding power supply system SIRIUS 3RV29, significantly reduces the main circuit wiring. The circuit breakers 3RV2 replace the proven series 3RV1. Simple, efficient, always up to date - the SIRIUS system modular concept.
