The current
I
max
provides information about the performance of the solid-
state relay. The actual permitted rated operational current
I
e
can be
smaller depending on the connection method and cooling conditions.
Note:
The required heat sinks for the corresponding load currents can
be determined from the characteristic curves
(see page 6/59,
"More Information")
. The minimum thickness values for the
mounting surface must be observed.
