The ABB 1SBL281022R8010 is a reliable capacitor duty contactor designed specifically for switching capacitor banks in industrial power factor correction systems. As part of the ABB UA capacitor switching contactor series, it is engineered to manage the high inrush currents generated during capacitor energisation while providing dependable switching performance in industrial electrical installations.
This contactor features integrated damping resistors to reduce current peaks when capacitor banks are switched on. Its compact three-pole design, screw terminal connections and built-in auxiliary contact make it suitable for automatic power factor correction panels, electrical distribution equipment and industrial automation systems.
With a 220–230 V AC coil supply, three main poles, a 30 A capacitor switching rating and a 690 V AC rated operational voltage, the ABB UA30-30-10RA provides a dependable solution for capacitor bank control and reactive power compensation applications.
Capacitor duty contactors such as the ABB UA30-30-10RA are designed to safely control capacitor banks where very high transient currents can occur during energisation. The integrated damping resistors help reduce electrical stress and improve the reliability of power factor correction equipment.
The ABB UA series provides a dedicated switching solution for reactive power compensation systems, helping industrial installations improve energy efficiency and maintain stable electrical performance.
