Why Choose the Lovato BFK1210A04860 Power Factor Correction Contactor?
The Lovato BFK1210A04860 is a three-pole power factor correction contactor designed specifically for switching capacitor banks in industrial and commercial power factor correction systems. Part of the Lovato BFK12 contactor series, it incorporates limiting resistors to control the high inrush currents associated with capacitor switching.
The BFK1210A04860 provides a maximum IEC AC-6b operational power rating of 12.5 kvar at 400 V, with additional ratings of 7 kvar at 230 V, 14 kvar at 440–480 V and 16 kvar at 690 V. Its three normally open main poles provide reliable switching of three-phase capacitor stages in automatic power factor correction equipment.
Featuring a 48 V AC 60 Hz control coil, a rated insulation voltage of 690 V and an IEC conventional free-air thermal current of 28 A, the BFK1210A04860 provides a purpose-built solution for capacitor switching. Screw terminals and support for 35 mm DIN rail or screw mounting simplify integration into power factor correction panels.

Reliable Capacitor Switching for Power Factor Correction
Power factor correction contactors are specifically engineered for switching capacitor banks, where energisation can produce substantially higher transient currents than conventional loads. The Lovato BFK1210A04860 incorporates limiting resistors to manage these capacitor switching conditions and provide reliable operation in automatic power factor correction equipment.
With an AC-6b rating of 12.5 kvar at 400 V, the BFK1210A04860 is suited to individual capacitor stages in low-voltage PFC banks. Its three-pole configuration, 48 V AC 60 Hz control coil and flexible mounting options make it straightforward to integrate into new or existing power factor correction panels.
Typical Applications
- Automatic power factor correction capacitor banks.
- Low-voltage power factor correction panels.
- Three-phase capacitor switching.
- Industrial electrical distribution systems.
- Commercial and industrial switchboards.
- OEM power factor correction equipment.
