                              The contactors are fully rated up to 3000 meters. Following are derating multipliers for altitudes above 3000 meters for both voltage and current:

                              Voltage
                              3500m x 0.90
                              4000m x 0.80
                              4500m x 0.70
                              5000m x 0.60

                              Current
                              3500m x 0.92
                              4000m x 0.90

                              5000m x 0.86

                              For example, an LC1D80 at 5000 meters:
                              - The maximum rated operational voltage is 1,000V (IEC947-4) and 690V (UL/CSA). At 5000 meters it becomes 1000V x 0.6 = 600V (IEC947-4) and 690V x 0.6 = 414V (UL/CSA).
                              - The maximum rated operational AC3 current is 80A. At 5000 meters it becomes 80A x 0.86 = 68A.
