Reliable Capacitor Switching for Power-Factor Correction
Capacitor banks can generate very high transient currents when energised, placing substantially greater demands on switching equipment than conventional resistive or motor loads. ABB UA contactors are specifically designed to withstand these capacitor-switching conditions and provide reliable switching in industrial reactive-power compensation systems.
The UA95-30-00 is particularly suited to automatic power-factor correction panels where capacitor stages must be repeatedly connected and disconnected as electrical demand changes. Its three-pole configuration, high peak-current capability and application-specific AC-6b rating make it a dependable switching component for three-phase capacitor banks.
Typical Applications
- Automatic power-factor correction panels.
- Three-phase capacitor-bank switching.
- Reactive-power compensation systems.
- Industrial electrical distribution panels.
- Power-factor correction equipment.
- Commercial and industrial capacitor installations.
- OEM electrical control and compensation systems.
