VS1-24 Indoor Vacuum Circuit Breaker
VS1-24 indoor vacuum circuit breaker is used as an indoor switchgear of 24kV power system and a control and protection unit in both electric network
equipment and power equipment in industrial enterprise and mine.Owing to its unique advantages, the circuit breaker is especially applicable to the frequent
operation of rated working current or the operation with repeated open and close of short circuit. Product complies with the standards GB1984 & IEC62271-100.
The circuit breaker features an integrated design to combine operating mechanism and circuit breaker itself into one.
It could be used as a stationary installation unit or assembled into cart unit with some special driving mechanism.
