Indoor Vs1 12kv 1250A Withdrawable High Medium Voltage Vacuum Circuit Breaker

Product description

VS1 series is a kind of indoor high voltage vacuum circuit breaker which is 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.
