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:
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
