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
-10 0.89
-5 0.91
0 0.92
+23 1.00
+30 1.03
+40 1.08
+55 1.16
Example: Rated current = 5 A, Environmental temperature = 40 °C, --> Correction factor =
1.08, Resulting current = 5.5 A --> Fount to next higher rated current: 6 A
