Reliable Capacitor Switching for Power Factor Correction Panels

Power factor correction contactors are designed to switch capacitor stages safely and repeatedly in automatic capacitor banks. When capacitors are energised, high transient inrush current can occur. The Lovato BFK2600A57560 uses built-in limiting resistors to help reduce these current peaks, supporting longer contactor life and more stable capacitor bank operation.

The 20 kvar at 400 V rating makes this model suitable for medium capacitor bank stages where compact installation, reliable AC control operation and repeatable switching performance are required. Its dedicated 575 V AC 60 Hz coil, BFK26 frame, high electrical endurance and IP20 front protection make it straightforward to integrate into professional power factor correction panels.

Typical Applications

• Automatic power factor correction capacitor banks.
• Reactive power compensation panels.
• Industrial electrical distribution systems.
• Capacitor switching stages up to 20 kvar at 400 V.
• Commercial and industrial energy management systems.
• Low-voltage switchgear and control panels.
• OEM power factor correction equipment.
• 60 Hz installations requiring a 575 V AC control coil.
