Why Choose the ABB 1SBL351024R8000 UA50-30-00RA Capacitor Contactor?
The ABB 1SBL351024R8000 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..RA capacitor contactor series, the UA50-30-00RA provides controlled switching of capacitive loads while limiting high inrush currents through integrated damping resistors.
This contactor is engineered for installations where capacitor switching currents can significantly exceed normal operating current levels. The integrated precharging resistors help reduce current peaks during capacitor energisation, improving system reliability and extending electrical service life.
With a rated reactive power capability of 40 kvar at 400 V AC, a 220–230 V AC 50 Hz / 230–240 V AC 60 Hz coil and a three-pole main contact configuration, the ABB 1SBL351024R8000 is suitable for industrial power factor correction panels and capacitor bank switching applications.
