1) Please observe operational voltage.
2) Assignment and short-circuit protective devices according to
IEC 60947-4-1:
The contactor or starter must not endanger persons or the installation in the
event of a short-circuit.
Type of coordination "1": The contactor or the starter may be non-operati-
onal after every short-circuit release.
Type of coordination "2": The contactor or the starter must be operational
after a short-circuit release (without replacement of parts). There is a risk of
contact welding.
3) Contactors not mountable.
4) Please ensure that the maximum AC-3 operational current has sufficient
safety clearance from the rated current of the fuses.
5) With 3UF18 68-3GA00 current transformer.
