Circuit breaker, S0, motor protection, Class 10, A-release 20-25A, N-release 325A – 3RV20214DA20

Circuit breaker size S0 for motor protection, CLASS 10 A release 18...25 A N-release 325 A spring-type terminal standard switching capacity SIRIUS 3RV2 circuit breakers for motor protection for safe shutdown in case of short circuit and protection of loads and systems against overload, as well as for safe disconnection of the system from the mains. The compact and climate-proof circuit breakers are optimized for use in feeder circuits due to their low heat dissipation, also for IE3/IE4 motors. Worldwide approvals (e.g. IEC and UL/CSA) and applications in hazardous areas (ATEX or IEC Ex) are a matter of course. Device versions 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 are available with screw or spring-type terminals for quick, maintenance-free and vibration-resistant connection, and optionally with integrated auxiliary switch. The comprehensive range of accessories, such as auxiliary switches, auxiliary releases, signaling switches, etc., is uniform for all sizes. The use of various power supply options, such as the associated SIRIUS 3RV29 infeed system, significantly reduces main circuit wiring. The 3RV2 circuit breakers replace the proven 3RV1 series. Simple, efficient, always up to date - the SIRIUS modular system.
