Main conductors: Busbar connections
•
Auxiliary and control conductors: Screw terminals

DC solenoid system with 3TC44 reversing contactor for series
resistor
1)
On this version, a magnetic system is used in the DC economy circuit.
A varistor can be retrofitted. A 3TC4417-4A.. reversing contactor is included in
the scope of delivery of the vacuum contactor.
2)
For use of 3TF6 vacuum contactors in the environment of frequency
converters, we recommend ordering a special version:
3TF6...-
....
-Z A02
.
3TF68/3TF69 vacuum contactors in their basic version are supplied with inte-
grated overvoltage damping for the main current paths. The surge suppres-
sion circuit is not required for operation in circuits with DC choppers,
frequency converters or speed-variable operating mechanisms, for example.
The circuit could be damaged by the voltage peaks and harmonics and thus
cause phase-to-phase short circuits. For this reason, the contactors can also
be supplied without integrated overvoltage damping. Without additional price.
The article number must be supplemented by
"–Z"
and the order code
"A02"
.
3)
When using 3TF68 vacuum contactors with IE3/IE4 motors from 8.5 times the
starting current, please use 3TF69 vacuum contactors. For more information
about dimensioning and configuring,
see page 3/6
.
4)
Please inquire about use of 3TF69 vacuum contactors with IE3/IE4 motors.
5)
On this version, a magnetic system with rectifier
is used in the DC economy
circuit. Varistor integrated. A 3TC4417-
....
reversing contactor with preassem-
bled connecting cable (approx. 1 m) and plug is included in the scope of sup-
ply of the vacuum contactor.
For accessories and spare parts,
see pages 3/137 to 3/140.
