Test periods and currents for gG and gM fuse links

1) Ich: with gM fuse links the time/current characteristic is specified through gates in Table 3 DIN VDE 0636 Part 10.
With short-circuit current, fuses limit the short-circuit current before the peak value is
reached, see current limitation diagram, Fig. 7-7.
Fuse links whose rated currents are in the ratio of 1:1.6 respond selectively up to
690 V rated voltage at rated currents ≥ 16 A.
