Derating is not shown in the documentation.

The derating factors to be applied for main pole operational voltage and current of GV7R are as follows:
Altitude (m)                                                          2000                      3000                     4000                     5000
Rated operational voltage (V) Ue                            690                        550                       480                       420
Average thermal current (A) at 40 °C                      1xIn                       0.96xIn                 0.93xIn                 0.9xIn
