The derating of the permissible rated current for installation altitudes of
over 1000 m and at ambient temperatures below 45 °C is calculated as
follows:
Total derating = Derating
K = K x K
1 2
It must be borne in mind that total derating must not be greater than 1!
Example: Altitude: 3000 m
Ambient temperature: 35 °C
→ Total derating = 0.845 x 1.125 = 0.95
