Derating
Temperature derating
Coolant inlet temperature: In the temperature range +45 °C (+113 °F) to +50 °C
(+122 °F), the rated output current is decreased by 2% for every additional 1 °C (1.8 °F).
The output current is calculated by multiplying the current given in the rating table by the
derating factor.
Example: If the coolant inlet temperature is 47 °C (+117 °F), the derating factor is
100% - 2%/°C · 2 °C = 100% - 4% = 96% = 0.96. The output current is then 0.96 ×

Ambient temperature: In the ambient temperature range +50 °C (+122 °F) to +55 °C
(+131 °F), the rated output current is decreased by 1% for every additional 1 °C (1.8 °F).
The output current is calculated by multiplying the current given in the rating table by the
derating factor.
Example: If the ambient temperature is 52 °C (+126 °F), the derating factor is
100% - 1%/°C · 2 °C = 100% - 2% = 98% = 0.98. The output current is then 0.98 ×

Altitude derating
At altitudes from 1000 to 4000 m (3281 to 13123 ft) above sea level, the derating is 1% for
every 100 m (328 ft). If the installation site is higher than 2000 m (6600 ft) above sea level,
contact the local ABB representative.
