Internal Fuse
The CD3000E thyristor unit have internal fuse extrarapid at low I²t for the thyristor protection of against
the short-circuits.
The fuse must have I²t lower than the thyristor one (I²t max)

Caution:
The Fuses must have I²t 20% less than thyristor's I²t.
Caution:
High speed fuses are used only for the thyristor protection and can not be used to
protect the installation.
Caution:
The warranty of thyristor is null if no proper fuses are used. See tab.
Warning:
The user installation must be protected by electromagnetic circuit breaker or by
fuse isolator.
