Stationary Derating Coefficient
The table below indicates deratings for each type of products.
|Type||Stationary Derating Coefficient|
Deratings for Ambient Temperatures
The following Deratings for Ambient Temperatures are required:
Regard the peak current as stationary current when current waveform is repeated pulse or AC waveform. Do not use the effective value of the current waveform.
