The Lovato BFK8000A400 is a three-pole power factor correction contactor designed for switching capacitor banks in industrial power factor correction systems. Part of the Lovato Electric BFK series, it incorporates limiting resistors to manage the demanding switching conditions associated with power factor correction capacitors.
Designed with an AC control circuit, the BFK8000A400 provides a maximum IEC operational power of 50 kvar at 400 V. Its dedicated capacitor-switching design makes it suitable for automatic power factor correction panels and other installations where capacitor banks must be reliably connected and disconnected.
The contactor features a 400 V AC 50/60 Hz coil, three poles and a conventional free-air thermal current of 115 A at temperatures up to 40 °C. It can be installed using screws or on a 35 mm DIN rail, providing flexible integration into industrial electrical panels.
Power factor correction systems use capacitor banks to compensate for reactive power in electrical installations. Contactors used for capacitor switching must accommodate the particular electrical stresses created when capacitors are connected, making a dedicated power factor correction contactor an important part of a reliable installation.
The Lovato BFK8000A400 is specifically designed for this role and includes limiting resistors for capacitor switching. With AC-6b operational ratings across several system voltages, it provides a purpose-built switching solution for industrial power factor correction equipment.
