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]

+10
+23
+40

Correction factor

Example: Rated current = 10 A; Environmental temperature = 60 °C; --> Correction factor
= 1.21; Resulting current = 12.1 A --> Fount to next higher rated current: 13 A
