Important information:
Performance diagrams:
In order to reach the prescribed current values, mounting
must take place on a finned heat sink or a cooling plate. The
performance diagrams show how the thermal resistance of
the heat sink appropriate to the relay can be determined
independently of the load current and the ambient tempera-
ture.
The thermal resistance only applies to heat sinks with verti-
cal cooling ribs. A safety factor (30%) must be taken into
account under difficult conditions (e.g. switching cabinet
without ventilation...).
Maximum surge current:
If loaded with the maximum surge current, the permitted
junction temperature is exceeded. A temporary loss of block-
ing ability can be anticipated. It is necessary to disconnect
from the mains. Switching on again is permitted only after
cooling down to the crystal temperature permitted for normal
operation. The maximum surge current may be utilized only
occasionally, i.e. in the event of a malfunction.
