Current ratings

The power ratings for the 480V, 575V and 690V configurations are shown below.

The continuous current ratings given are for a maximum ambient temperature of 40°C (104°F) and an altitude of 1000m (3,300ft). For operation at higher temperatures and altitudes de-rating is required. Overload of 150% for 30s is available with ambient temperature of 40°C (104°F) up to a maximum of 10 repetitions per hour.
