Why Choose the Lovato BFK1810A57560 Power Factor Correction Contactor?
The Lovato BFK1810A57560 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 capacitor switching duties and incorporates limiting resistors to reduce the high inrush currents associated with energising capacitors.
The BFK1810A57560 provides a maximum IEC operational power rating of 15 kvar at 400 V and features a dedicated 575 V AC 60 Hz coil. Its three normally open main contacts provide three-phase capacitor switching, while the dedicated BFK construction makes it suitable for automatic 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 BFK1810A57560 is engineered for demanding low-voltage installations. Its screw-connected main circuit provides secure termination for integration into power factor correction panels and electrical control cabinets.

Reliable Capacitor Switching for Power Factor Correction
Power factor correction contactors such as the Lovato BFK1810A57560 are specifically engineered for switching capacitor stages in reactive power compensation systems. Capacitors can generate 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 BFK1810A57560 provides 15 kvar at 400 V AC-6b and combines dedicated capacitor switching characteristics with a 575 V AC 60 Hz coil. Its three-pole configuration and robust electrical ratings 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.
- 60 Hz installations using a 575 V AC control supply.
