Siemens Circuit breaker for motor protection 22A

Circuit breaker size S0 for motor protection, CLASS 10 A release 16...22 A N release 286 A screw connection. Standard switching capacity of SIRIUS 3RV2 circuit breakers for motor protection to ensure safe disconnection in case of short circuits and to protect consumers and systems from overload, as well as to safely isolate the system from the grid. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, naturally suitable for IE3/IE4 motors and equally 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), system 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 contacts. The comprehensive accessories, such as auxiliary contacts, 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 concept.
