Siemens Sirius 3RV2 S2 Motor Protection for transformer protection

Motor protector size S2 for transformer protection A-trip 28...36 A N-trip 820 A screw terminal Standard switching capacity Circuit breaker SIRIUS 3RV2 For transformer protection for reliable protection of transformers against short circuit and overload. Thanks to their low heat loss, these compact and climate-proof circuit breakers are optimized for use in load feeders, as well as for IE3/IE4 motors, of course. Worldwide approvals (e.g., IEC and UL/CSA) and uses in hazardous areas (ATEX or IEC Ex) are standard. 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 terminals for fast, maintenance-free and vibration-proof connection and optionally with integrated auxiliary switch. The extensive range of accessories, such as auxiliary contacts, auxiliary releases, signal switches etc. are standardized for all sizes. The use of various energy supply options, such as the associated SIRIUS 3RV29 insertion system, significantly reduces wiring in the main circuit. 3RV2 circuit breakers replace the well-proven 3RV1 series. Simple, effective and always up to date - SIRIUS modular system.
