Circuit breaker, size S2, for motor protection, CLASS 10 A trip, 28...36 A, N-trip 520 A
S2-size circuit breaker for motor protection, CLASS 10 A trip, 28...36 A, N-trip 520 A, screw terminal, standard switching capacity. SIRIUS 3RV2 circuit breakers for motor protection provide reliable disconnection in the event of a short circuit and protect loads and systems against overload, while also ensuring safe isolation of the system from the power supply.
Thanks to their low heat dissipation, these compact and climate-resistant circuit breakers are optimized for use in feeder circuits, including naturally for IE3/IE4 motors. Worldwide approvals (e.g. IEC and UL/CSA) as well as 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 networks.
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, signalling switches, etc., is standardized across all frame sizes. The use of various power supply options, such as the matching SIRIUS 3RV29 feeder 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.
