Project Description

Contactor for capacitor KML

The new KML contactors are designed in compliance with IEC 60947-1 standard and are suitable for operating three-phase power capacitors.  Thanks to the block of preload build-in the same contactor, high currents peaks are reduced when connecting the capacitors and protecting as well the contactor.

The block of preload consists of three auxiliary contacts of preclosing, along with resistance (two by phase) through which the capacitors are preconnected to the network, cushioning therefore the peaks of connection current. Once the preload resistances have reduced the current peaks that take place in the connection of the capacitor, automatic opening of the auxiliary contacts occurs with the objective of not having unnecessary losses.
