Why Choose the Lovato BFK1810A400 Power Factor Correction Contactor?
The Lovato BFK1810A400 is a specialised three-pole power factor correction contactor designed for reliable switching of capacitor banks in industrial and commercial electrical installations. As part of the Lovato BFK18 contactor series, it is specifically engineered for AC-6b capacitor switching duties and incorporates limiting resistors to reduce the high inrush currents associated with energising capacitors.
The BFK1810A400 provides an IEC AC-6b operational power rating of 15 kvar at 400 V and features a 400 V AC 50/60 Hz coil. A built-in 1NO auxiliary contact provides an additional normally open contact for signalling, interlocking and control functions within power factor correction equipment.
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 BFK1810A400 is engineered for dependable capacitor switching. 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 BFK1810A400 are specifically engineered for switching capacitor stages in reactive power compensation systems. 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 during switching.
The BFK1810A400 provides 15 kvar at 400 V AC-6b and combines dedicated capacitor switching characteristics with a 400 V AC 50/60 Hz coil. Its three-pole design, built-in auxiliary contact 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 panels.
- Three-phase capacitor bank switching.
- Reactive power compensation systems.
- Capacitor switching stages up to 15 kvar at 400 V.
- Industrial and commercial electrical distribution installations.
- OEM power factor correction equipment.
