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 1.05
40 1.12
50 1.20
60 1.30
Example: Rated current = 5 A; Environmental temperature = 50 °C; --> Correction factor =
1.2; Resulting current = 6.0 A
