Why Choose the Lovato BFK1810A04860 Power Factor Correction Contactor?
The Lovato BFK1810A04860 is a specialised three-pole power factor correction contactor designed for reliable capacitor bank switching in industrial and commercial electrical installations. As part of the Lovato BFK18 contactor series, it is specifically designed for AC-6b capacitor switching duties and incorporates limiting resistors to reduce the high inrush currents associated with energising capacitor stages.
The BFK1810A04860 provides a maximum IEC operational power rating of 15 kvar at 400 V, with additional AC-6b ratings of 9 kvar at 230 V, 17 kvar at 440–480 V and 20 kvar at 690 V. Its dedicated 48 V AC 60 Hz coil makes it suitable for power factor correction systems using a 48 V AC, 60 Hz 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 BFK1810A04860 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.
