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]
-5
0
+10

Correction factor

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
