Circuit breaker, S0, motor protection, Class 10, A-release 2.8-4A, N-release 52A - 3RV20211EA10

Circuit breaker size S0 for motor protection, CLASS 10 A release 2.8...4 A N-release 52 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 from 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 load feeders due to their low heat dissipation, naturally 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), 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-type terminals for a fast, maintenance-free and vibration-proof connection, and optionally with 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 the main circuit wiring. The 3RV2 circuit breakers replace the proven 3RV1 series. Simple, efficient, always up-to-date - the SIRIUS modular system.
