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.
