The Indoor high voltage Vacuum circuit breaker are used in the AC three-phase power system of frequency 50HZ. The rated voltage of VCB can be 12kV, 24kV or 36kV. It has advantages of small size,reliable insulation, and long time free maintenance etc. The operating mechanism can be modular or spring ,VS1 vacuum circuit breakers can either be a fixed installation unit or be a withdrawable unit with a dedicated pushing framework.
This series is a retrofit solution for truck-mounted circuit breakers,which makes it possible to replace only the components of the circuit breaker that are subjected to the greatest stresses during long-term reliable operation, instead of the entire switchgear panel, allowing for the replacement of switchgear on a "plug-and-play principle".
