DESCRIBE

The ABB UA110-30 contactor is a three-pole capacitor-duty contactor designed for switching capacitor banks and reactive power compensation circuits in industrial electrical systems. It belongs to ABB’s UA series of contactors, which are engineered for applications where load switching involves high inrush currents, especially when capacitor banks are energized. These contactors incorporate features that help limit peak currents and ensure reliable operation in demanding power factor correction and capacitor switching applications. They are suitable for use in panel boards, power distribution, and automated switching systems.
