■ Selection and ordering data
1)
The type current provides information about the performance capacity of
the solid-state relay. The actual permitted rated operational current I
e
can
be smaller depending on the connection method and cooling conditions.
2)
Please note that this version can only be used for a rated current of up to
approx. 50 A and a conductor cross-section of 10 mm
