Voltage transformer circuit breaker, size S00 1.4 A, N-trigger 6 A, 1W with horizontal auxiliary switch, SIRIUS 3RV1 circuit breaker for distance protection for use in conjunction with voltage transformers. The compact and climate-resistant circuit breakers are optimized for use in consumer branches due to their low heat dissipation, and are naturally suitable for IE3/IE4 motors. Worldwide approvals (such as IEC and UL/CSA) and applications in explosion-hazardous environments (ATEX or IEC Ex) are standard. The voltage transformer circuit breakers are available with three different rated currents. Optional side auxiliary switches are available as accessories. Simple, efficient, always up to date - the SIRIUS system modular concept.
