Product Description

Product Description

ZN63-24  is  a  series  of  indoor  high-voltage  vacuum  circuit breakers for three-phase AC power systems with a rated voltage of 24kV  and  a frequency  of 50Hz .
It  serves  as  an  indoor  switching device for power grid equipment and  industrial and  mining  power equipment, providing protection and control.   The circuit breaker is suitable for frequent operations at the rated current or for multiple interruptions  of  short-circuit  currents. It  features  an
operating mechanism  and  a  dedicated  propulsion  mechanism,  forming  a trolley unit for specific applications .

Service Condition

Altitude	≤2000m (if the altitude increases , the rated insulation level should be correspondingly increased)
Ambient Air Temperature	Upper limit +60 ° C , Lower limit -40 ° C
Seismic Intensity	≤8 degrees
Relative Humidity	Daily average ≤95% , Monthly average ≤90%
Suitable for places without fire, danger, severe pollution , chemical corrosion , and severe vibration
