Low-voltage capacitor banks APCQ

Contactor-switched capacitor banks for power factor compensation

The Hitachi Energy's capacitor banks series APCQ provides the ideal power factor correction solution for industrial and commercial networks. The benefits are:

  • Solving utility penalty charges due to low cos φ 
  • Improving energy efficiency
  • Releasing additional capacity or increasing system load without additional equipment
  • Increasing service life time of infrastructure


The APCQ low-voltage contactor-switched capacitor bank can be used in industrial and commercial networks buildings. Industry segments where the product can be used include:

  • Mining 
  • Steel
  • Chemical
  • Pulp and paper
  • Cement
  • Plastics
  • Printing
  • Food industries
