Contactor for capacitors, with series resistors, 12.5 kVAr, 24 V 50 Hz
for switching in central compensation systems with 180-fold transient peaks. The capacitors are pre-charged via the early-make auxiliary contacts and the fitted wire resistors, thus reducing the inrush current.

Standards	In the case of group compensation multi-stage capacitor banks are connected to the mains, as required. Transient currents of up to 180 × Ie could flow between the capacitors. The capacitors are pre-charged via the early-make auxiliary contacts and the fitted wire resistors, thereby reducing the inrush current. The main contacts then close in a time-delayed manner and bring about the continuous current. Due to their special contacts, the contactors for the capacitors are weld-resistant for capacitors with inrush current peaks Due to their special contacts, the contactors for capacitors are weld-resistant for capacitors with inrush current peaks up to 180 × le.
