Electrical Characteristics:
Times vs current characteristics
The curves shown on page 4 indicate the pre-arcing time for each rated current as a function of RMS
value of pre-arcing current I:
-
Tolerances on this current ± 8%
-
Beyond 30 sec, small overloads must be eliminated by another device.
-
Curve CC’ represents the maximum times taken by the associated device to clear small overloads; only its
horizontal line is represented.
Its oblique line must be plotted according to sketch in top right corner:
-
The intersection of the fuse and CC’ curves indicates the minimum breaking current I
pm
of the fuse.
