добавлять "для защиты от к.з." можно, но не нужно, так как плавкий предохранитель защищает от к.з. по умолчанию

Fuse-switch combination
Back-up fuses are commonly used in fuse-switch combinations,
both in open air and in gas insulated panels. When a fuse-switch
combination operated as a protective device by tripping a system,
the fuse assumes two different functions depending on the interrupted current value. When the fault current is greater than the transfer current, the fuse simply extends the breaking capability of the switch disconnector by completing the interruption operation faster than the incorporated switch. This happens when the fuse clearing time is shorter than the total opening time of the Load Break Switch (LBS). By the time the striker pin pops up, the
fuse has already cleared the fault current and the switch opens
in almost no load conditions. If the fault currents are less than
the nominal transfer current, the fuse then uses the striker pin to
activate the switch, which in turn causes the system to trip. In
other words, the interruption process is completed by the switch to
prevent overloading of the fuses in situations where the fault
current is low. Fuses used in fuse-switch combinations have to
fulfill conditions specified in IEC 62271-105 (former IEC 60420
and IEC 420). Back-up fuses are specially designed for such an
application.
