Derating

The load capacity (current and power) decreases if the installation site altitude exceeds 2000 metres
(6600 ft), or if the ambient temperature exceeds 45°C (113°F).

Temperature derating

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 ambient temperature is 50°C (+122°F), the derating factor is 100% - 1
90% or 0.90. The output current is then 0.90 × I
Note: I

Altitude derating

At altitudes from 2000 to 4000 m (6600 to 13123 ft) above sea level, the derating is 1% for every 100 m
(328 ft). For a more accurate derating, use the DriveSize PC tool. If the installation site is higher than
2000 m (6600 ft) above sea level, please contact your local ABB representative or office for further
information.
