• ZN85-40.5 Indoor High Voltage Vacuum Circuit Breaker

  Summary

  ZN85-40.5(3AV3) indoor high voltage vacuum circuit breaker is of rated voltage 40.5kV, three-phase and AC 50/60Hz. It applies to mining firms, power house and substation acting as protection and control electric apparatus. It is also applicable in occasions with frequent operation.

  Ambient condition

  1. Altitude: ≤1000m;
  2. Ambient temperature: -25℃~+40℃;
  3. Relative humidity: daily average ≤95％, monthly average ≤90％;
  4. Earthquake intensity: ≤8 degree;
  5. Applicable occasions should free from inflammables, explosives, corrosives
  and severe vibration.

  Structure feature

  1. The arc-extinguish chamber is on the upper part and the mechanism is on the lower part. This structure is convenient for debug.
  2. Complex insulating structure using air and organic material; Compactable dimension and small weight.
  3. Vacuum arc-extinguish chamber of Cutler-Hammer Company (USA) and domestic ZMD are both applicable for the VCB. Both two
  kinds of chambers extinguish arc by vertical magnetic field and featuring with low cut-off and good on-off capability with asymmetry.
  4. Simple spring operation mechanism is free from maintenance within 10000 times of operations.
  5. Lead-screw propeller, easy and stable operation and good self-locking capability.
