ABB 1SBL181024R8110 UA16-30-10RA three-pole capacitor switching contactor with 24 V AC coil designed for industrial power factor correction applications.
£134.18
The ABB 1SBL181024R8110 is a specialised UA16-30-10RA three-pole capacitor switching contactor designed for reliable control of capacitor banks in industrial power factor correction systems. As part of the advanced ABB UA capacitor contactor series, it is engineered to manage high inrush currents generated during capacitor energisation while providing dependable switching performance.
This contactor features ABB's dedicated capacitor switching technology with integrated damping resistors to limit current peaks when capacitor banks are energised. The compact block design includes three main poles and one built-in normally open auxiliary contact, making it suitable for efficient integration into industrial electrical panels.
With a 24 V AC coil, 12.5 kvar capacitor switching capability at 400 V AC and a compact DIN rail or panel mounting format, the ABB 1SBL181024R8110 is ideal for power factor correction equipment and industrial control systems requiring reliable capacitor switching.
Capacitor switching contactors are designed specifically for controlling capacitor banks used in industrial power factor correction systems. Unlike standard contactors, ABB UA16-30-10RA contactors incorporate damping resistors to help manage high current peaks during capacitor energisation.
The ABB 1SBL181024R8110 provides a compact and reliable switching solution for electrical engineers and panel builders designing efficient industrial power distribution and energy management systems.
