## **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 112] intentionally omitted <==**

**----- Start of picture text -----**<br>
Ambient Temperature [°C] Correction factor<br>-5 0.87<br>0 0.90<br>+10 0.95<br>+23 1.00<br>+30 1.04<br>+40 1.10<br>+50 1.15<br>+60 1.20<br>**----- End of picture text -----**<br>


Example: Rated current = 5 A, Environmental temperature = 40 °C, --> Correction factor = 1.1, Resulting current = 5.5 A --> Round to next higher rated current: 6 A
