SIEMENS SION, 3AK & 3AH Vacuum Circuit Breakers provide safe and reliable medium-voltage power distribution and stand out for their long service life. In addition to standard applications in medium-voltage power distribution, our portfolio also covers applications for specific requirements in the generator or rail fields. Type tests as specified in IEC 62271-100 are performed as a rule for all Siemens circuit breakers. Generator circuit breakers are additionally tested in accordance with IEEE C37.013 or IEC / IEEE 62271-37-013. This standard is the only standard worldwide to take into account the increased requirements which the devices are subjected to when switching generators. As a result the standard has been enhanced to a Dual Logo IEEE/IEC leading standard.
EATON Medium Voltage (MV) Vacuum Circuit Breakers are a series of vacuum circuit breakers that are compliant with international, national and industry standards. This series of circuit breakers is mainly suitable for medium voltage power distribution systems and provides centralized, integrated control and protection for medium voltage energy equipment, generators, motors, feeder lines and for power transmission and distribution used in civil, industrial, commercial, mining and marine applications.
