LIFASA automatic capacitor banks are used for centralized compensation of power factor in low voltage installations.

These equipments are supplied completely assembled and ready for use: it is only necessary to connect it to the mains with cables of adequate cross section, and to supply the operation signal from a suitable current transformer.


LIFASA automatic capacitor banks are composed of the following elements:

  • High rupturing capacity (HRC) fuses connected to a busbar system.
  • Contactors specially adapted to the work with capacitors.
  • Inrush current limiting inductances.
  • Fast discharge resistors.
  • Low losses power capacitors.
  • Reactive power controllers.
  • Terminals for neutral and ground conductors.
  • Metal cabinet containing all the switchgear.


  • Equipments wired and tested at works, full finished and supplied with all control and safety devices.
  • Easy transportation and installation due to their light weigh.
  • Easy selection of the most appropriate cos φ to avoid penalty charges on tariffs.
  • Long life and high reliability, thank to the use of self-healing and low losses capacitors.
  • Wide range of power (from 5 to 1600 kvar, 440 V) with standard equipments for immediate delivery.
  • Option of including various accessories.


On request, automatic capacitor banks can be produced to customers special requirements. Among the different possibilities are the following:

  • Other voltages and frequencies.
  • Capacitor banks with different degrees of protection.
  • Capacitor banks for outdoor installation.
  • Working program 1:2:4:4:, 1:2:4:8:, 1:1:2:2:.
  • Fixed step (for transformer compensation).
  • Higher powers than the above stated.
