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 0.87
0 0.90
+10 0.95
+23 1.00
+30 1.04
+40 1.10
+50 1.15
+60 1.20
Example: Rated current = 5 A; Environmental temperature = 40 °C; --> Correction factor =
1.1; Resulting current = 5.5 A --> Fount to next higher rated current: 6 A
