The actual power dissipation the fuse determined:
The ratio between the operational current and the rated current
of the fuse 380 550 0,69.
The power dissipation 0,44 77W= W. ratings.
From the curve P/Pn=f(I/In) given the fuse manufacturer,
the ratio P/Pn thus determined, and this example 0,44.
From the table for OESA 400R_ maximum ratings seen that
the operational current (380A) well the fuse power dissipation
