Circuit breaker, S0, motor protection, Class 10, A-release 14-20A, N-release 260A – 3RV20214BA15

Circuit breaker size S0 for motor protection, CLASS 10 A release 13...20 A N-release 260 A screw connection standard switching capacity with transverse auxiliary switch 1S+1O SIRIUS 3RV2 circuit breakers for motor protection for reliable short-circuit disconnection and protection of loads and the system against overload, as well as for reliable disconnection of the system from the mains. The compact and climate-proof circuit breakers are optimized for use in load feeders due to their low heat dissipation, of course also for IE3/IE4 motors. Worldwide approvals (e.g. IEC and UL/CSA) and applications in potentially explosive atmospheres (ATEX or IEC Ex) are a matter of course. 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 are available with screw or spring-loaded terminals for a fast, maintenance-free and vibration-proof connection, and optionally with an integrated auxiliary switch. The comprehensive accessories, such as auxiliary switches, auxiliary releases, signaling switches etc., are 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.
