Product Description

 ZN63-12 indoor high-voltage vacuum circuit breaker is an indoor switchgear of three-phase AC 50HZ power system with rated voltage of 12kV, which is used as the protection and control unit of power grid equipment and power equipment of industrial and mining enterprises. It is suitable for frequent operation under rated working current or places where short circuit current is broken for many times. The circuit breaker adopts an integrated design of operating mechanism and circuit breaker body, which can be used as a fixed installation unit or equipped with a special propulsion mechanism to form a handcart unit.

1.Ambient air temperature: upper limit+40 ℃, lower limit - 15 ℃;

2.Altitude: ≤ 1000m (if it is necessary to increase the altitude,the rated insulation level shall be increased accordingly)

3.Amplitude: seismic train degree shall not exceed 8 degrees;

4.The daily average value of air relative humidity shall not be greater than 95%, and the monthly average value shall not be greater than 90%
5.in places where there is no fire, danger, serious pollution, chemical corrosion and severe vibration.
