## **Effect of ambient temperature** 

The units are calibrated for an ambient temperature of +23°C. To determine the rated current for a lower or higher ambient temperature, use a correction factor (typical value) from the table below: 

**==> picture [314 x 99] intentionally omitted <==**

**----- Start of picture text -----**<br>
Ambient Temperature [°C] Correction factor<br>-10 0.89<br>-5 0.91<br>0 0.92<br>+23 1.00<br>+30 1.03<br>+40 1.08<br>+55 1.16<br>**----- End of picture text -----**<br>


Example: With a nominal current of 5A and an ambient temperature of 40°C, a correction factor of 1.08 results. This results in a nominal current of 5.5 A, which is rounded up to the next higher nominal current 6 A.
