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

2)
Please note that the version with spring-type terminals can only be used for
a rated current of up to approx. 20 A and a conductor cross-section of
2.5 mm

. Higher currents can be achieved by connecting two conductors
per terminal.
