SIVACON S8 Planning Principles – In-line design, plug-in
Connection is effected directly at the switching device The
maximum cable cross sections that can be connected are
stated in the device catalogues. The in-line switch-discon-
nector allows the installation of a measuring instrument for
single-pole measurement. For three-pole measurement,
the measuring instruments can be installed in the device or
cable compartment door. The associated current transform-
ers are integrated into the in-line unit on the cable feeder
side.
The plug-in design for SIVACON S8 switchboard (Fig. 5/1)
with switching devices in in-line design with an incom-
ing-side plug contact allows easy and fast modification or
replacement under operating conditions. The pluggable
in-line units are operated directly at the device. Tab. 5/1
gives an overview of the general cubicle characteristics.
