Reversing contactors supplied: 3TC44 17-4A..
For accessories, see page 3/134, for spare parts, see page 3/144.
1) Built-in overvoltage damping: varistor circuit.
2) For more information on EMC, see LV 1 T .
3TF68/69 vacuum contactors are supplied with integrated overvoltage
damping for the main conducting paths (for description, see LV 1 T). The
overvoltage damping circuit is not required if 3TF68/69 contactors are
used in circuits with DC choppers, frequency converters or speed-
variable drives, for example. It could be damaged by the voltage peaks
and harmonics and cause phase-to-phase short-circuits.
For this reason, the contactors can also be supplied without integrated
voltage damping. Without additional charge.
The order number must include "-Z" and the order code "A02".
* You can order this quantity or a multiple thereof.
