What is the function of daping resistor used with the capacitor switching contactors ?

The capacitor switching contactors are equipped with block of early make poles and damping resistors to limit the value of the current on closing to 60 In Max.

This current limitation increase the life time of all the components of the installation specificlly the fuses and the capacitors

The patented design of the add-on block ensures safety and long life of installation
