Why Choose the Lovato BFK3800A024 Power Factor Correction Contactor?
The Lovato BFK3800A024 is a compact and robust 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 BFK38 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 30 kvar at 400 V, with additional capacitor switching ratings of 17 kvar at 230 V, 33 kvar at 440 to 480 V and 36 kvar at 690 V. It uses a 24 V AC 50/60 Hz coil, making it suitable for low-voltage industrial control circuits used in capacitor bank and power factor correction panels.
With 3 normally open main poles, 56 A conventional free air thermal current, screw or 35 mm DIN rail mounting, IP20 terminal protection when correctly wired and recognised international approvals, the BFK3800A024 is a dependable choice for capacitor switching stages where compact size, controlled inrush performance and long service life are required.

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 BFK3800A024 uses built-in limiting resistors to help reduce these current peaks, supporting longer contactor life and more stable capacitor bank operation.
The 30 kvar at 400 V rating makes this model suitable for larger capacitor bank stages where compact installation, reliable AC control operation and repeatable switching performance are required. Its 24 V AC 50/60 Hz coil, BFK38 frame, controlled inrush design 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 30 kvar at 400 V.
- Commercial and industrial energy management systems.
- Low-voltage switchgear and control panels.
- OEM power factor correction equipment.
