Siemens 3RV28214CD10 3RV2821-4CD10 circuit breaker, S0 transformer protection, UL 489, CSA C22.2

Circuit breaker size S0 for transformer protection with approval circuit-breaker UL 489, CSA C22.2 NO.5-02 A-release 22 A N-release 364 A screw connection standard switching capacity SIRIUS 3RV2 circuit breaker for transformer protection in accordance with UL 489/CSA C22.2 No.5 for short-circuit protection of systems and transformers in systems designed in accordance with UL. The compact and climate-resistant circuit breakers are optimized for use in load feeders due to their low waste heat, and of course also for IE3/IE4 motors. Worldwide approvals (e.g. IEC and UL/CSA) and applications in potentially explosive applications (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 connections for a quick, maintenance-free and vibration-proof connection, and optionally with a built-in auxiliary switch. The comprehensive range of accessories, such as auxiliary switches, auxiliary releases, signaling switches, etc., is standardized for all sizes. The use of various power feed options, such as the associated SIRIUS 3RV29 feed 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.
