The ABB 1SBL281024R8010 is a three-pole capacitor duty contactor, designated as UA30-30-10RA. This contactor is designed specifically for switching capacitor banks in industrial applications where very high peak currents can occur, such as power factor correction systems. It includes built-in damping resistors that help limit inrush current when capacitors are energized and supports pre-charging of capacitor circuits. The device is suitable for AC control voltages and offers robust performance and durability in demanding electrical environments.
