Contactor for capacitor switching:
Type: 3TS11.. to 3TS15.. and
3TS21.., 3TS22.., 3TS25..
IS/IEC:60947-4-1
3TS11..-0A..5-8K
3TS21..-0A..5-8K
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.
• Insulation Voltage Ui = 690 V AC,
Temperature: Storage -25 to +55ºC
Service (without derating) -25 to +40ºC
Use the devices with the declared capacitor bank ratings only.

Operating Instructions
Hazardous Voltage can cause Electric
Shock and burns.
Disconnect Power before proceeding with
any work on this equipment.
Avoid operation during under voltage
conditions. Switch only onto discharged
capacitors. Manual operation not permitted
for function testing.
Commissioning and maintenance by
qualified personnel only. Follow the
operating instructions.
Do not remove precharging resistors. If
contactor is switched on load without resistor,
it may cause damage to the contactor.
Additional Aux:
Facility to add-on 1NO or 1NC auxiliary contact block
type 3TX40.. is available for 3TS11.., 3TS1200, 3TS1300,
3TS1400, 3TS1500, 3TS21.., 3TS2200, 3TS2500
3TX 40.. Block fitment (For 3TS11.., 3TS1200, 3TS1300,
3TS1400, 3TS1500, 3TS21.., 3TS2200, 3TS2500)
Aux Contact Rating:
3TX40
Ie AC-15 = 3.6A at 415V
Ie DC-13 = 0.48A at 220V
Note: Do not remove precharging resistors. If contactor is
switched on load without resistor, it may cause damage to
the contactor.
iii) Control circuit:
• Control voltage is marked on the coloured identification
tag on the coil.
Note:
• The voltage is to be maintained within allowable limits.
• Operation on under voltage conditions to the coil may
cause damage to the coil/contactor.
• Maximum back-up fuse rating for control circuit = 16A
= 6A if relay contact is in the control circuit.
