Circuit breaker, S0, motor protection, Class 10, A-release 5.5-8A, N-release 104A - 3RV20211HA10

Circuit breaker size S0 for motor protection, CLASS 10 A-release 5.5...8 A N-release 104 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 consumers and systems against overload, as well as for safe disconnection of the system from the mains. Thanks to their low heat dissipation, the compact and climate-proof circuit breakers are optimized for use in consumer feeders, of course also for IE3/IE4 motors. Global 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 trip units, 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.
