Siemens SIEM circuit breaker

Circuit breaker size S0 for transformer protection A-trigger 0.11...0.16 A N-trigger 3.3 A screw connection standard switching capacity. SIRIUS 3RV2 circuit breakers for transformer protection provide safe protection for 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 they are naturally suitable for IE3/IE4 motors as well as for switching direct current. Global approvals (e.g., IEC and UL/CSA) and applications in explosion-prone environments (ATEX or IEC Ex) are standard. Device 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 are optionally available with built-in auxiliary switches. 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 3RV2 circuit breakers replace the proven series 3RV1. Simple, efficient, always up to date - the SIRIUS system modular kit.
