Siemens Circuit breaker 1 pc 3RV2431-4PA10

Circuit breaker size S2 for transformer protection A-trigger 28...36 A N-trigger 820 A screw connection standard switching capacity circuit breaker 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, and are of course suitable for IE3/IE4 motors. Worldwide approvals, such as IEC and UL/CSA, as well as applications in explosion-prone environments (ATEX or IEC Ex), are standard. Device variants are available for motor protection, including 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 an integrated auxiliary switch. The comprehensive accessories, such as auxiliary switches, auxiliary triggers, 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 circuit breakers 3RV2 replace the proven series 3RV1. Simple, efficient, always up-to-date - the SIRIUS system modular kit.
