Product Overview:
ZN63 (VS1) -12 indoor high-voltage vacuum circuit breaker is an indoor switchgear for three-phase AC 50Hz power systems with a rated voltage of 12kV. It serves as a protection and control unit for power grid equipment and industrial and enterprises. Suitable for places that require frequent operation at rated working current, or multiple disconnections of short-circuit current. The circuit breaker adopts an integrated design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or equipped with a dedicated propulsion mechanism to form a handcart unit.
Normal usage conditions:
Surrounding air temperature: upper limit+40℃, lower limit -15℃.
Altitude: ≤ 1000m (if altitude needs to be increased, the rated insulation level should be correspondingly increased).
Amplitude: The seismic intensity shall not exceed 8 degrees.
The daily average relative humidity of the air shall not exceed 95%, and the monthly average shall not exceed 90%.
A place without fire, explosion hazard, serious pollution, chemical corrosion, and severe vibration.
