CSC Duty Contactors are designed for safely switching capacitors without using choke-type inductors.

Since this operation is associated with high inrush current, all Gruppo Energia CSC Contactors are standardly equipped with six quick discharge damping resistors (two per phase) and three auxiliary contacts that limit peak current during the first stage of switching.

Finally, the nominal current is transferred through the main contacts, which are switched-on, while the auxiliary contacts are switched off.
