Why Choose the Lovato BFK2600A110 Power Factor Correction Contactor?
The Lovato BFK2600A110 is a compact and reliable three-pole power factor correction contactor designed for controlled capacitor bank switching in industrial electrical panels, reactive power compensation systems and automatic power factor correction assemblies. As part of the Lovato BFK26 series, it is purpose-built for AC-6b capacitor switching duties and includes limiting resistors to help reduce high inrush current when capacitor stages are energised.
This contactor is rated for a maximum IEC operational power of 20 kvar at 400 V, with additional capacitor switching ratings of 11 kvar at 230 V, 22 kvar at 440 to 480 V and 25 kvar at 690 V. It uses a 110 V AC 50/60 Hz coil, making it suitable for industrial control circuits used in automatic capacitor bank panels.
With 3 normally open main poles, 45 A conventional free air thermal current, screw or 35 mm DIN rail mounting, IP20 terminal protection when correctly wired and recognised international approvals, the BFK2600A110 is a dependable choice for medium capacitor switching stages where compact size, controlled inrush performance and long service life are required.

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 BFK2600A110 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 110 V AC 50/60 Hz coil, BFK26 frame, high electrical endurance and IP20 front protection make it straightforward to integrate into professional power factor correction panels.
