Effect of ambient temperature
The units are calibrated for an ambient temperature of +23°C. To determine the rated cur-
rent for a lower or higher ambient temperature, use a correction factor (typical value) from
the table below:
Ambient temperature [°C] Correction factor
-5 0,85
+10 0,95
+23 1,00
+40 1,08
+60 1,21
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
