11.1.1
Performance reduction during elevated ambient temperatures
The maximum permissible temperature for the rated current at rated voltage is speci
fi
ed as rated
temperature.
Since the dissipation of the power loss (heat development) in the device is decisively dependent on
the ambient temperature, the max. load must be reduced at an ambient temperature above the rated
temperature (see following table)!
The average value measured during a 24 h period must be 5 K under the max. ambient temperature.
For installation in a switch cabinet, the device
’
s dissipation and its possible affect on the ambient
temperature must be taken into consideration!
