The mains contactors listed here assume the network’s
rated current (I
LN
) without mains choke or mains filter.
Their selection is based on the thermal current (AC-1).
Caution!
Jog mode must not be used through the mains contactor
(rest period f 180 s between switching off and on)

When the frequency inverter works at its rated current
limit, the frequency inverter’s greatest possible output
voltage (U
2
) is , due to the mains choke, reduced to about
96 % of the mains voltage (U
LN
).

For technical data of the DE4-LN mains chokes, see the
installation instructions AWA8240-1711, for those of the
DDK series, see the main Industrial Switchgear catalog.
h
Mains chokes reduce the magnitude of the current
harmonics up to about 30 % and increase the lifespan of
frequency inverters and upstream-connected switching
devices.
