Compensation Contactors
ABB Electrification
Very high peak currents occur during capacitor energizing. UA..RA contactors are designed with a damping resistor to withstand peak current points without limitation.
Advantages of the product
Widest range of contactors on the market up to 80 Kvar
Reliable in application requiring capacitor switching
Easy selection with CAPCAL software.
Product features
UA..RA contactors with damping resistors are used when peak currents exceed 100 times the rated rms current
UA contactors are used when peak currents are less than or equal to 100 times the rated rms current
UAF..RA with wide control voltage range thanks to AF technology and electronic coil.
