Product Overview

ZW32-12F outdoor high voltage vacuum demarcation circuitbreaker is an outdoor power distribution device witha rated voltage of12kV, three-phase Ac, 50HZ . The circuit breaker ismainly used for breaking and closing load current, overload currentand short circuit, quick-breaking, grounding protection, optionalreclosing times, local remote control and remote communication in thepower system. lt is suitable for substations and industrial and miningenterprises. Used for protection and control in electrical systems

Working Environment

  1.Ambient air temperature:-40℃~+40℃:
  2. Altitude: no more than 2000m:
  3. The wind speed does not exceed 34m/'s lequivalent to 700Pa on the cylindrical surfacel;4. Pollution level: Grade i:
  5. There is no frequent severe vibration, and the earthguake intensity does not exceed 8 degrees6. There is no fire,explosion, chemical corosion place.

Main fnctions of the controller
