Why Choose the Lovato BFK1810A02460 Power Factor Correction Contactor?
The Lovato BFK1810A02460 is a compact three-pole power factor correction contactor designed specifically for switching capacitor banks in industrial power factor correction systems. Part of the Lovato BFK18 series, it incorporates limiting resistors for capacitor switching and provides a maximum IEC operational power rating of 15 kvar at 400 V.
Purpose-built for capacitor switching duties, the BFK1810A02460 combines three main poles with a built-in 1NO auxiliary contact. Its electrical characteristics include a 32 A conventional free-air thermal current, 690 V rated insulation voltage and 6 kV rated impulse withstand voltage, supporting reliable operation in appropriately rated power factor correction equipment.
This specific variant uses a 24 V AC, 60 Hz control coil. Its AC-6b operational power ratings include 9 kvar at 230 V, 15 kvar at 400 V, 17 kvar at 440–480 V and 20 kvar at 690 V, while screw or 35 mm DIN rail mounting enables straightforward installation in electrical control panels.

Reliable Capacitor Switching for Power Factor Correction
Power factor correction systems use capacitor banks to compensate for reactive power in electrical installations. When capacitor stages are energised, high transient inrush currents can occur, so dedicated capacitor contactors use features such as limiting resistors to support reliable repeated switching.
The Lovato BFK1810A02460 is specifically designed for this application, combining limiting resistors with a 15 kvar rating at 400 V and a dedicated 24 V AC, 60 Hz control coil. Its compact BFK18 construction and flexible mounting options make it suitable for integration into automatic power factor correction panels.
Typical Applications
- Automatic power factor correction panels.
- Industrial capacitor bank switching.
- Reactive power compensation systems.
- Electrical distribution and control panels.
- OEM power factor correction equipment.
- Capacitor switching stages rated up to 15 kvar at 400 V.
- 60 Hz installations requiring a 24 V AC control coil.
