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 sim-
pler 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
Other rated control supply voltages on request.
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 start-up conditions.
