■ 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 depend-
ing on the connection method and cooling conditions.
2)
Please note that the version with an M4 screw connection can only be used
for a rated current of up to approx. 50 A and a conductor cross-section of
10 mm
2
.
3)
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
2
. Higher currents are possible by connecting two conductors per
terminal.
