£505.19
The ABB UA75-30-00 (1SBL411022R8600) 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 to manage capacitor switching applications where high inrush currents occur during energisation.
This contactor features a robust block-type design with an AC-operated control circuit using a laminated magnet system. The UA75 series is designed for switching capacitor banks where inrush current peaks are less than or equal to 100 times the nominal RMS current, helping provide dependable operation and long electrical service life.
With a 400–415 V AC 50 Hz / 415–440 V AC 60 Hz control coil, a 690 V AC rated operational voltage and a three-pole configuration, the ABB UA75-30-00 is suitable for industrial capacitor switching and power factor correction installations.
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.
