Power loss for fixed-mounted molded case circuit breakers
Thermal-magnetic overcurrent releases (TM)
The table below shows the
power loss and the current path resistance for thermal-magnetic
overcurrent releases (TM)
. 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.
