No, you don't understand. It is a THERMAL fuse. It must be IN
the oven to do any good. There is definitely no excess room
inside of the 10811 to add a fuse holder.
For a thermal fuse to make any use, it needs to be in the oven, but for
pure over-current protection and external normal fuse will work, which
is what he proposes. However, the trouble with dimensioning a normal
fuse is that it needs to survive the heatup period, where as for a
run-away oven the heatup never ends. The setability of the current limit
of a fuse isn't particularly great so that it can be distinguished.
The only way to achieve any meaningfull protection will be a thermal
fuse. Only very little additional protection is achieved by a normal fuse.
