The GRUPPO ENERGIA CSC series contactors are designed only for capacitor switching.
When capacitors start to operate they cause a high frequency and a current about 180 times higher than rated current for several milliseconds.
This may results in welding main contactsof standard duty contactors and/or results in capacitors damages. So the shock inductance is to be fixed to each phase to limit this current. This is pratically achieved by means of a block of auxiliary contacts with quick discharge damping resistors (two each phase). Thus the peak current is limited within the contactor making capacity. The GRUPPO ENERGIA CSC SERIES CONTACTORS can be safely used in single step or multiple step capacitor banks because of their special design and the life time of both capacitors and circuit protection devices are greatly increased.
