Siemens Indus.Sector Circuit Breaker 3RV2811-1HD10

Circuit breaker size S00 for transformer protection with approval circuit-breaker UL 489, CSA C22.2 NO.5-02. A-trip 8 A, N-trip 163 A, screw connection. Standard switching capacity of SIRIUS 3RV2 circuit breakers for transformer protection according to UL 489/CSA C22.2 No.5 for short-circuit protection of systems and transformers in UL-designed installations. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, naturally also for IE3/IE4 motors and equally for switching direct current. Worldwide approvals (e.g., IEC and UL/CSA) and applications in explosion-hazardous environments (ATEX or IEC Ex) are standard. 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 come with screw or spring connection for a quick, maintenance-free, and vibration-resistant connection, and optionally with an integrated auxiliary switch. The comprehensive accessories, such as auxiliary switches, auxiliary trip units, signaling switches, etc., are uniform across all sizes. The use of various power supply options, such as the associated power supply system SIRIUS 3RV29, significantly reduces the main circuit wiring. The 3RV2 circuit breakers replace the proven 3RV1 series. Simple, efficient, always up to date - the SIRIUS system modular design.
