£505.19
The ABB UA75-30-00 (1SBL411022R8800) is a specialised three-pole capacitor switching contactor designed for reliable control of capacitor banks in industrial power factor correction systems. As part of the ABB UA contactor range, it is engineered for switching capacitor banks where high inrush currents occur during energisation, providing dependable operation in industrial electrical installations.
This contactor features a robust block-type design with an AC-operated control circuit using a laminated magnet system. The UA75-30-00 is suitable for capacitor switching applications where inrush current peaks are less than or equal to 100 times the nominal RMS current, helping deliver reliable switching performance and long electrical service life.
With a 230–240 V AC 50 Hz / 240–260 V AC 60 Hz control coil, a 690 V AC rated operational voltage and a three-pole configuration, the ABB UA75-30-00 is ideal for industrial capacitor switching and power factor correction systems.
Capacitor switching contactors are designed specifically for controlling capacitor banks used in power factor correction systems. By managing high transient currents during energisation, specialised contactors such as the ABB UA75-30-00 help improve switching reliability and protect electrical components.
The ABB UA series provides dependable switching performance for industrial electrical installations where frequent capacitor switching and long service life are required.
