Circuit breaker, S3, for motor protection, CLASS 10, A-release 45-63A, N-release 819A – INN 3RV20414JA10

Circuit breaker size S3 for motor protection, CLASS 10 A-release 45...63 A N-release 819 A screw terminal standard switching capacity Circuit breaker SIRIUS 3RV2 for motor protection for safe shutdown in the event of a short circuit and protection of loads and the plant against overload, as well as for safe disconnection of the plant from the mains. The compact and climate-proof circuit breakers are optimized for use in feeder branches due to their low heat dissipation, and of course 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 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 are available with screw or spring-loaded terminals for 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.
