Description

Product Description

This series of medium-voltage vacuum contactors uses specialized vacuum intterupters for switching capacitor banks. They undergo a high-current aging process and are securely assembled with insulation supports and metal frames into a solid unit, which is safe and reliable. This series of high-voltage vacuum contactors have large stroke, strong breaking ability, small bounce of closing and opening brake, stable coil working performance, and good triphase synchronization, especially suitable for switching the load of switching capacitor banks. There are electromagnetic holding type and permanent magnet mechanism type, and they can be used as a switching switch in the compensation device of capacitor banks with large capacitance less than 3000kvar.

Feature

  • The metal frame is firmly integrated into one unit, which is safe and reliable.

  • The mechanism has a large stroke, strong breaking ability, and small bounce of closing and opening.

  • The coil has stable working performance, and good triphase synchronization.
