Siemens 3TS1722-0A 5-8K Series User manual

s
Contactor for capacitor switching:
Type: 3TS1722-0A..5-8K
IEC 60947-4-1
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 is 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.
