Why Choose the Lovato BFK1810A23060 Power Factor Correction Contactor?
The Lovato BFK1810A23060 is a specialised three-pole power factor correction contactor designed for reliable capacitor bank switching in industrial electrical panels, reactive power compensation systems and energy management installations. As part of the Lovato BFK18 contactor series, it is purpose-built for AC-6b capacitor switching duties and includes limiting resistors to help reduce inrush current when capacitor stages are energised.
This contactor provides an IEC operational power rating of 15 kvar at 400 V, with additional capacitor switching ratings of 9 kvar at 230 V, 17 kvar at 440–480 V and 20 kvar at 690 V. Its dedicated 230 V AC 60 Hz coil makes it suitable for 60 Hz control circuits requiring a 230 V AC control supply.
With a conventional free-air thermal current of 32 A, rated insulation voltage of 690 V and rated impulse withstand voltage of 6 kV, the BFK1810A23060 provides robust electrical performance for capacitor switching applications. Screw fixing or 35 mm DIN rail mounting enables straightforward integration into automatic power factor correction panels and electrical control cabinets.

Reliable Capacitor Switching for Power Factor Correction
Power factor correction contactors such as the Lovato BFK1810A23060 are specifically engineered for switching capacitor stages safely and repeatedly. Capacitors can produce substantial transient inrush currents when energised, so the BFK design incorporates limiting resistors that help reduce these current peaks and the resulting electrical stress on the contactor and capacitor bank.
The BFK1810A23060 provides 15 kvar at 400 V AC-6b and combines dedicated capacitor switching characteristics with a 230 V AC 60 Hz coil. Its three-pole configuration, robust electrical ratings and panel-friendly mounting options make it suitable for automatic power factor correction equipment in industrial and commercial installations.
Typical Applications
- Automatic power factor correction capacitor banks.
- Reactive power compensation panels.
- Three-phase capacitor bank switching.
- Capacitor switching stages up to 15 kvar at 400 V.
- Industrial electrical distribution systems.
- Commercial and industrial energy management systems.
- OEM power factor correction equipment.
- 60 Hz installations requiring a 230 V AC control coil.
