## **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 75] intentionally omitted <==** **----- Start of picture text -----**
Ambient temperature [°C] Correction factor
-5 0,85
+10 0,95
+23 1,00

+60 1,21
**----- End of picture text -----**
Example: Rated current = 10 A; Environmental temperature = 60 °C; --> Correction factor = 1.21; Resulting current = 12.1 A --> Fount to next higher rated current: 13 A ## **Variants** **==> picture [274 x 133] intentionally omitted <==** **----- Start of picture text -----**
