VCB Fixed- Type Indoor Vacuum Circuit Breaker With High Voltage12KV/ 40.5KV​ 

 

1. General Features

ZN12 -40.5 series indoor high voltage vacuum circuit breaker applied to power system that of 35KV three-phase AC 50HZ. It is using the longitudinal magnetic field contacts for the ceramic structure,the proliferation of breaking arc generated when current distribution in the contact on the same local melting phenomenon does not occur, but also has a low arc energy voltage (20-200V) and low chopping current (4-5A), and operate with high reliability organizations.

 

2. Environmental Condition

  • Altitude:not exceed 2000m
  • Ambient temperature:not higher than +40°C, not less than -10°C
  • Relative humidity:daily average relative humidity:≤95%;monthly average relative humidity≤90%;daily average saturated vapor pressure ≤2.2KPa;monthly average value ≤1.8KPa
  • Earthquake intensity:≤8 degree
  • The installation should be free from fire,explosion,severe vibration,chemical corrosion and serious pollution
