Siemens Circuit breaker, S2, class 10

Circuit breaker size S2 for motor protection, CLASS 10 A release 28...36 A N release 520 A screw connection. Standard switching capacity circuit breaker SIRIUS 3RV2 for motor protection to safely disconnect in case of short circuits and to protect consumers and installations from overload, as well as to safely isolate the installation from the power supply. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, naturally also suitable for IE3/IE4 motors and equally for switching direct current. Worldwide 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 optionally with built-in auxiliary switches. The extensive 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 circuit breakers 3RV2 replace the proven series 3RV1. Simple, efficient, always up-to-date - the SIRIUS system modular concept.
