Why Choose the Lovato BFK2600A048 Power Factor Correction Contactor?
The Lovato BFK2600A048 is a specialised three-pole power factor correction contactor designed for reliable switching of capacitor banks in industrial and commercial electrical installations. As part of the Lovato BFK26 contactor series, it is specifically developed for capacitor switching duties and incorporates limiting resistors to help control the high inrush currents associated with energising capacitor stages.
The BFK2600A048 provides a rated reactive power of 20 kvar at 400 V, 50 Hz and features a 48 V AC 50/60 Hz coil. Its three normally open main contacts provide three-phase switching, while the absence of built-in auxiliary contacts makes it a straightforward solution for dedicated capacitor bank switching applications.
With a conventional free-air thermal current of 45 A, rated insulation voltage of 690 V and rated impulse withstand voltage of 6 kV, the BFK2600A048 is engineered for dependable industrial operation.

Reliable Capacitor Switching for Power Factor Correction
Power factor correction contactors such as the Lovato BFK2600A048 are specifically engineered for switching capacitor stages in reactive power compensation systems. Capacitors can generate substantial transient inrush currents when energised, so the BFK design incorporates limiting resistors that help control these current peaks and reduce electrical stress during switching.
The BFK2600A048 combines a 20 kvar rating at 400 V, 50 Hz with a 48 V AC 50/60 Hz coil. Its three-pole configuration, high insulation rating and flexible mounting options make it suitable for automatic power factor correction equipment in industrial and commercial installations.
Typical Applications
- Automatic power factor correction panels.
- Three-phase capacitor bank switching.
- Reactive power compensation systems.
- Capacitor switching stages rated up to 20 kvar at 400 V, 50 Hz.
- Industrial and commercial electrical distribution installations.
- OEM power factor correction equipment.
- Control systems using a 48 V AC 50/60 Hz supply.
