Reliable Capacitor Switching for Power Factor Correction
Power factor correction systems use capacitor banks to compensate for reactive power in electrical installations. Switching capacitor stages requires contactors specifically designed for AC-6b duty and capable of handling the electrical conditions associated with capacitor energisation.
The Lovato BFK1810A024 is specifically designed for this application and incorporates limiting resistors for capacitor switching. Its 15 kvar rating at 400 V, 32 A thermal current rating and 24 V AC 50/60 Hz control coil make it a purpose-built switching component for appropriately rated industrial power factor correction systems.
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 15 kvar at 400 V.
