Capacitor Switching Contactor

ABB Capacitor switching application leads to very high current peak at capacitor energization. UA..RA contactors are designed with damping resistor to handle current peaks without limitation. Product benefits include Widest contactor range on the market up to 80 Kvar; Reliable in capacitor switching demanding application & Easy selection with CAPCAL software. Product features include UA..RA contactors, with damping resistors, are used when peak currents are far exceeding 100 times nominal rms current; UA contactors are used when peak currents are less or equal to 100 times nominal rms current & UAF..RA with wide control voltage range available, thanks to AF technology and electronic coil.
