Why Choose the Lovato BFK1810A048 Power Factor Correction Contactor?
The Lovato BFK1810A048 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 incorporates limiting resistors to reduce the high inrush currents associated with capacitor switching.
The BFK1810A048 provides a maximum IEC AC-6b operational power rating of 15 kvar at 400 V and features a 48 V AC 50/60 Hz coil. Its capacitor-switching design makes it particularly suitable for automatic power factor correction panels where dependable operation and reduced switching stress are required.
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 BFK1810A048 is engineered for demanding low-voltage installations. Screw fixing or 35 mm DIN rail mounting allows straightforward integration into power factor correction panels and electrical control cabinets.
