Derating Factor
NOTE:
Altitude compensation in CWM Series contactors, considers a factor according to which the rated power must be reduced.
The derating of the permissible operating power for installation altitudes
above 1,500 m (5,000 ft) is calculated according to:
Total derating = Derating
current
x Derating
voltage
Example: Altitude: 3,000 m (10,000 ft):
Derating current K1 = 0.85
Derating voltage K2 = 0.88
Total derating = 0.85 x 0.88 = 0.75 x HP
