Time-current characteristics
Above, left: Curves idicating 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
- The intersection of the fuse and CC’ curves indicates the
minimum breaking current of the fuse.

Maximum values of total operating I
2t
and total operating times
Left: Horizontal curves indicating the maximum values of total
operating I2t (I2tt) as function of the prospective current Ip at 660
V, cos w = 0.15.
The vertical lines indicate the corresponding total operating time
Tt, with pre-arcing time in brackets.
