Box Type - Industrial PFC Capacitors

  • The Box Cap (metalized polypropylene) capacitor series has been designed for power factor correction in low-voltage plants.
  • The power range is from 1 kVAr to 50 kvar for a single capacitor container.
  • PFC capacitor modules are available for single- or three- phase applications in normal/heavy-duty & Super Heavy Duty design.
  • Modules contain the required number of single-phase capacitors in delta connection.
  • The capacitors are housed in a single rectangular steel case and are connected to three offset screw terminals (terminal block).
  • This construction enables simple and inexpensive installation on site and saves inventory costs on spare.
