Selection and ordering data
Selection notes
The solid-state contactors are selected on the basis of details of
the network, the load and the ambient conditions. As the solid-
state contactors are already equipped with an optimally
matched heat sink, the selection process is considerably
simpler than that for solid-state relays.
The following procedure is recommended:
•Determine the rated current of the load and the mains voltage
•Select a solid-state contactor with the same or higher rated
current than the load
1)
The type current provides information about the performance of the solid-
state contactor. The actual permitted rated operational current
I
e
can be
smaller depending on the connection method and installation conditions.
