High-Capacity Capacitor Switching for Power Factor Correction
Power factor correction systems use capacitor banks to compensate for reactive power within electrical installations. Switching high-capacity capacitor stages requires contactors specifically designed for AC-6b duty and capable of handling the electrical conditions associated with capacitor energisation.
The Lovato BFK15000A400 is purpose-built for this application and incorporates limiting resistors for capacitor switching. Its 100 kvar rating at 400 V, 165 A thermal current rating and 400 V AC 50/60 Hz control coil make it suitable for appropriately rated industrial power factor correction equipment.
Typical Applications
- Automatic power factor correction panels.
- High-capacity industrial capacitor bank switching.
- Reactive power compensation systems.
- Industrial electrical distribution panels.
- Power factor correction equipment and control cabinets.
- Capacitor switching stages rated up to 100 kvar at 400 V.
