For Normal domestic 100Amp Fuses to BS 1361, these are the graph given figures of TIME V. CURRENT, to Rupture the fuse:-
0.1 second @ 1800Amps
1 second @ 950Amps
5 seconds @ 630Amps
3 MINUTES @ 360Amps
10 MINUTES @ 250Amps - (Fuse does get Hot)
1 HOUR @ 170Amps
You should not plan an installation which relies on this though, the fuse will weaken with time as it is subjected to such overloads and the terminals etc of the cutout won't necessarily be rated for the duty.
