• JCZ5-12kV 160A 250A 400A 630A AC Three Pole H.V Vacuum Contactor

  Item No: JCZ5-12kv

  Application:

  The JCZ5-7.2 and JCZ5-12 series indoor AC high voltage vacuum contactor, it is divided into closing mechanical keeping and electromagnetic keeping two forms. This contactor is suitable for three phase AC 50Hz, rated voltage 7.2kV and 12kV, rated current up to 630A electricity power system, for long-distance making and breaking circuit, control such as the high voltage motor, transformer and capacitive load electrical equipment, especially suitable for the frequent operation. This contactor has the small shape, light weight, the assembled structure adopts the international popular layout of packaged up and down, convenient use and maintenance.

  Features:
  1. High reliability: The vacuum contactor has almost no wear when breaking the arc, ensuring stability during high-frequency operation.
  2. Long life: The vacuum interrupter has a longer service life, a long maintenance cycle, and reduces operating costs.
  3. Low maintenance requirements: Since the internal components are in a vacuum, the impact of external factors such as oxidation and corrosion on the equipment is reduced.

  Normal working conditions

  1) Altitude above sea should not be over 1,000m;

  2) Ambient temperature is -5°C~+40°C;

  3) Average temperature in 24 hour limited below 35°C;

  4) When the highest temperature is 40°C, the relative humidity should not be higher than 50%;

  5) Pollution degree: class 3
