For other types of fuses (TPA and GMT), if a fuse holder without a fuse is connected to a load,
the corresponding sensor remains inactive and no failure is indicated.
The maximum current capacity of each power bus circuit is 100 Amps. The total output current
capacity of the fuses on each bus must, therefore, not exceed 100 Amps. The maximum current
rating is marked on the fuse platform rear side. The power dissipation of the panel is 80 watts
maximum per fuse platform (40 watts per bus at 100 Amps).
Note: The continuous output load of the equipment during normal operation should not
exceed 80% of the rated value of the fuse. This allows some room for manufacturing
tolerances and voltage fluctuations in the plant power mains.
