Circuit breaker, size S00, for motor protection, CLASS 10, A-release 9...12.5 A, N-release 163 A
Circuit breaker, size S00, for motor protection, CLASS 10, A-release 9...12.5 A, N-release 163 A, screw terminal, standard switching capacity, with side-mounted auxiliary switch 1 NO + 1 NC. SIRIUS 3RV2 circuit breaker for motor protection, for safe disconnection in the event of a short circuit and for protecting loads and the system against overload, as well as for safe isolation of the system from the mains.
The compact and climate-resistant circuit breakers are optimized for use in load feeders due to their low heat dissipation, and are naturally also suitable for IE3/IE4 motors. Worldwide approvals (e.g. IEC and UL/CSA) and applications in hazardous areas (ATEX or IEC Ex) are, of course, available. 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 systems.
They are available with screw or spring-loaded terminals for quick, maintenance-free, and vibration-resistant connection, and optionally with an integrated auxiliary switch. The comprehensive range of accessories, such as auxiliary switches, auxiliary releases, signaling switches, etc., is standardized across all frame 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.
