Electronic trip units (ETU / LCD-ETU)
The table below shows the
power loss for electronic trip units (ETU / LCD-ETU)
. The power
loss applies for I
n
with 3-phase balanced load. The specified power loss is the sum of all
current paths.
The current path resistance is only a guide value and can fluctuate.
