Product Information 
The ZN85-40.5 series indoor high-voltage vacuum circuit breaker is suitable for three-phase AC 50Hz, rated voltage 40.5kV power system. It can be used for switching load current, overload current and fault current in industrial and mining enterprises, power plants and substations. The circuit breaker and the operating mechanism are arranged up and down, which effectively reduces the depth of the circuit breaker.
It meets the requirements of GB/T1984-2014 (AC HV circuit breaker) and JB355-1996 (3.6KV-40.5KV indoor AC HV vacuum circuit breaker). It can be used in the switchgear of KYN61.

 

Applicable conditions

• Ambient temperature: -10ºC-+40ºC
• Relative humidity: daily average 95. monthly average 90.
• Earthquake intensity: 8 degrees;
• Saturated vapor pressure: the average pressure of a day should be no more than 2.2kPa; the average pressure of a month should be no more than 1.8Kpa;
• The height above sea level:≤1000 m (Except special requirements)
• Applicable occasions should be free from inflammable, explosives, corrosives and severe vibration.
