Power loss

Power loss for fixed-mounted circuit breakers
Thermomagnetic overcurrent trip units (TM)
The table below shows the power loss and the current path resistance for thermomagnetic
overcurrent trip units (TM). The power loss applies for I
specified power loss is the sum of all current paths. The current path resistance is only a
guide value and can fluctuate.
