1P 3P 630A Indoor Fixed High Voltage Vacuum Circuit Breaker

VS1-24/630A indoor fixed high voltage vacuum circuit breaker

product description

Product name: VS1-24 indoor high voltage vacuum circuit breaker
Category: high voltage components
Product introduction: VSl-24 indoor high-voltage vacuum circuit breaker is an indoor switchgear with a three-phase AC 50Hz rated voltage of 24kV power system. It is used as a protection and control unit for power grid equipment and industrial and mining enterprise power equipment. It is suitable for places requiring frequent operation under rated industrial current, or multiple interruption of short-circuit current.

Applicable environment of VS1-24 indoor high voltage vacuum circuit breaker

A Ambient air temperature E upper limit +40℃, lower limit -15℃;
b Altitude: ≤1000m (if the altitude needs to be increased, the rated insulation level shall be increased accordingly);
c Amplitude: the seismic intensity does not exceed 8 degrees;
d The daily average value of air relative humidity is not more than 95%, and the monthly average value is not more than 90%
e A place free from fire, explosion, serious pollution, chemical corrosion and severe vibration.
