Expanding the contac-
tors of frame sizes S0 to
S3
With contactors of frame sizes S0 to S3, you can also attach 1-pole auxiliary
switch blocks instead of 4-pole auxiliary switch blocks.
The terminal markings of the 1-pole auxiliary switch blocks consist of
sequence numbers (location ID) on the basic unit and function numbers on
the auxiliary switch blocks.
