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

-10

0.89

-5

0.91

0

0.92

+23

1.00

+30

1.03

+40

1.08

+55

1.16

Example: Rated current = 5 A, Environmental temperature = 40 °C, --> Correction factor =

1.08, Resulting current = 5.5 A --> Fount to next higher rated current: 6 A
