Note: When the enclosure's thermal balance, consider the 4P devices load is only on 3 phases
Impedance calculation:
Z = P / I²
Z: impedance in Ohms
P: dissipated power in Watts (table values)
I: rating in Amperes
Voltage drop calculation:
U = P / I
U: voltage drop in Volts
P: dissipated power in Watts (table values)
I: rating in Amperes
The following table indicates the average dissipated power per pole in W for a
current equal to the rating of the device and at the operating voltage.
