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]

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

1.04; Resulting current = 5.2 A --> Fount to next higher rated current: 6 A
