Why Choose the Lovato BFK1210A400 Power Factor Correction Contactor?
The Lovato BFK1210A400 is a three-pole power factor correction contactor designed specifically for capacitor bank switching in industrial power factor correction systems. Part of the Lovato BFK12 series, it features an AC control circuit with limiting resistors and is rated for a maximum IEC operational power of 12.5 kvar at 400 V.
Designed for AC-6b capacitor switching duties, the BFK1210A400 provides a purpose-built solution for controlling capacitor stages used in reactive power compensation systems. The integrated limiting resistors help manage the electrical demands associated with capacitor switching, while the built-in 1NO auxiliary contact provides additional control functionality.
With a 400 V AC 50/60 Hz coil, three main poles and flexible screw or 35 mm DIN rail mounting, the BFK1210A400 is well suited to industrial power factor correction panels and electrical control cabinets. Its capacitor switching ratings include 7 kvar at 230 V, 12.5 kvar at 400 V, 14 kvar at 440–480 V and 16 kvar at 690 V.

Reliable Capacitor Switching for Power Factor Correction
Power factor correction systems use capacitor banks to compensate for reactive power within electrical installations. Switching these capacitors requires contactors designed for AC-6b duty, allowing capacitor stages to be controlled reliably as demand within the electrical system changes.
The Lovato BFK1210A400 is specifically designed for this application and incorporates limiting resistors for capacitor switching. Its 12.5 kvar rating at 400 V and 400 V AC 50/60 Hz control coil make it suitable for appropriately rated stages in automatic power factor correction equipment.
Typical Applications
- Automatic power factor correction panels.
- Industrial capacitor bank switching.
- Reactive power compensation systems.
- Electrical distribution and control panels.
- Industrial power factor correction equipment.
- Capacitor switching stages rated up to 12.5 kvar at 400 V.
