Notes
The derating coefficient must be considered in accordance with the following table in order to determine the maximum permissible current loading at
different ambient temperatures.
Example:An NZM2-A250 should be operated at an ambient temperature of 65 °C.
How high is the permissible rated operational current I e ?
At 65 °C the derating coefficient is 0.85, this means I e = 250 A x 0.85 = 212.5 A.
The NZM2-A250 may be operated at an ambient temperature of 65 °C with a maximum I e = 212.5 A.
