sum of description:
ZN63A(VS1)-12 is a high-voltage indoor vacuum circuit breaker used as a protection and control unit for power grid equipment and industrial electrical equipment in the power system with a rated voltage of 7.2KV~12KV.It meets the requirements of GB/T1984-2014 (AC high-voltage circuit breaker) and JB355-1996 (3.6KV-40.5KV indoor AC high-voltage vacuum circuit breaker). It can be used in KYN28(GZS1), XGN, GG-1A switchgear.
Operating conditionsTemperature: -10℃~+40℃. Relative humidity: the daily average relative humidity is not more than 95%; the monthly average relative humidity is not more than 90%. Earthquake intensity: no more than 8. Saturated vapor pressure: the daily average pressure does not exceed 2.2kPa; the monthly average pressure does not exceed 1.8Kpa. Altitude: ≤1000 meters (special circumstances separately). This equipment should be installed in a place free from fire, explosion, severe dirt, chemical corrosion and severe vibration.
This model integrates the operating mechanism and the circuit breaker, with reasonable layout and beautiful and compact appearance.
This model can be operated frequently and can be opened and closed multiple times quickly.
Two installation methods (fixed or mobile) meet the needs of different switch cabinets.
