Tap selector connection contacts for multiple coarse change-
over selector VRC
In the case of multiple coarse change-over selectors, special attention must
be paid when routing the cables for connecting the tap selector connection
contacts and the multiple coarse change-over selector connection contacts.
These cables should be as far away as possible from neighboring connec-
tion contacts.
► Tap selector connection contacts that face both multiple course tap se-
lector columns must have at least 3 mm of paper insulation to ensure di-
electric strength.
In this regard, please also pay attention to the dimensional drawing on which
the order is based.
