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 BFK8000A230 uses built-in limiting resistors to help reduce these current peaks, supporting longer contactor life and more stable capacitor bank operation.

The 50 kvar at 400 V rating makes this model suitable for larger capacitor bank stages where high making capacity, controlled inrush limitation and reliable AC control operation are required. Its 230 V AC 50/60 Hz coil, BFK80 frame, 800 A RMS making capacity 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 50 kvar at 400 V.
• Commercial and industrial energy management systems.
• Low-voltage switchgear and control panels.
• OEM power factor correction equipment.
• Installations requiring a 230 V AC control coil.
