ABB Inc. 3-pole Contactors for Capacitor Switching UA95 ... UA110

Description UA contactors can be used for the switching of capacitor banks whose inrush current peaks are less or equal to 100 times nominal rms current. The capacitors must be discharges (maximum residual voltage at terminals ≤ 50 V) before being re-energized when the contactors are making. These contactors are of the block type design with: 3 main poles control circuit: AC operated add-on auxiliary contact blocks for front or side mounting and a wide range of accessories.
