You're apparently unaware of why the breaker is even there . . .
The Z-figures are intended to display various ARCHITECTURES,
not recommended wiring diagrams and bills-of-materials. In
the case of Z-16, it shows the use of fuseblocks in combination
with a CROWBAR over voltage protection system. A panel re-setable
breaker is one of the installation requirements for a crowbar
ov protection system. So when combining with fuseblocks, the
solitary breaker illustrated is part of the system integration
task.
Now, if your choice of power distribution protection is
breakers instead of fuses then the 5A breaker would be
right on the bus and labeled ALT FIELD. If you're
going to use some form of field disconnect ov protection
system, then yes, the 5A breaker could be a fuse . . . but
not an in-line . . . it would be one of many fuses on the
main bus.
The simple answer to your question depends on the
combination of components you're planning to use. In
all cases, an in-line fuse is not a recommended
substitute in any case. If you're using fuse blocks
AND have crowbar ov protection, then you need the breaker
as suggested.
