Operating Instructions
Contactor for capacitor switching:
Type: 3TS11 .. to 3TS15..
IS/IEC:60947
A. Technical Data
i) Main circuit:
The capacitors are precharged during pick-up via early-make
contacts and integrated pre-charge resistors before the main
contacts close.
This combination may be used for switching of Individual
capacitor for power factor correction of single loads or for
switching capacitor banks in parallel in centralized group
power factor correction system.

C. Maintenance
• Removedustbysuction.
• Replacementofcoilavailableasspare.
• Sparecontactkitsavailablefrom3TS12to3TS15.
• ContactSiemensSalesofcefordetails.
• Handletheresistorwirescarefully.
D. Note:
NormallythepowerfactorcontrollerinAPFCpanels,hasthe
provisionforadjustmentundervoltagecutoutwithrespect
to voltage and time. Please ensure that the controllers are
present as per values given in the table on right side.
