WHY a fusible link at ALL???
Why not an in-line fuse. Bussman has several in-line fuse holders
for larger *MAX* fuses up to 70 amps. The *MAX* are just larger ATC
blade types. The standard ATC fuses are only good to about 30A.
In-line fuse holders are sealed an very cool
Just a thought?

Fusible links are attractive for their robustness. No
vulnerable connections. Fabricated from wire, splices
and terminals for longevity and durability approaching that
of wire. They have fusing constants on a par with ANL
current limiters
http://www.aeroelectric.com/Mfgr_Data/Fuses_and_Current_Limiters/Bussman/ANL.pdf
and much slower than the ANN series limiters.

Fusing constants for the MAX series fuses can be
seen here . . .
http://www.aeroelectric.com/Mfgr_Data/Fuses_and_Current_Limiters/Bussman/MAX.pdf
Inline fuse holders for the plastic plug-in fuses
can be seen at:

The fusible link was suggested for uses in areas where
the robustness can be exploited but limited to situations
where probability of needing to operate as a protective
device was exceedingly low.
I've done anecdotal surveys during my presentations to
ask how many individuals present have had the fusible link
in an automobile open up. In over ten years of asking
the question, I think I've had two positive responses.
The MAX or ATC series fuses (or even breakers) can always
be considered to replace any fusible link shown in the
z-figures . . .

Yes, for instance the HHX fuseholder on p.15 goes up to 60A with 6AWG
leads. There is also a line of fusible links on p.9. Thanks Bob et
al for your help.
