Reliable Capacitor Switching for Power Factor Correction
Power factor correction contactors such as the Lovato BFK2600A024 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 reduce these current peaks and the resulting electrical stress during switching.
The BFK2600A024 provides 20 kvar at 400 V AC-6b and combines dedicated capacitor switching characteristics with a 24 V AC 50/60 Hz coil. Its three-pole design, high electrical endurance and flexible mounting options make it suitable for automatic power factor correction equipment in demanding industrial and commercial installations.
Typical Applications
- Automatic power factor correction panels.
- Three-phase capacitor bank switching.
- Reactive power compensation systems.
- Capacitor switching stages up to 20 kvar at 400 V.
- Industrial and commercial electrical distribution installations.
- OEM power factor correction equipment.
- Control systems using a 24 V AC supply.
