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

Example: Rated current = 5 A; Environmental temperature = 50 °C; --> Correction factor =
1.2; Resulting current = 6.0 A
