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:
When powered, the thyristor unit is subject to dangerous voltages; disconnect
from the power supply before opening the fuse box and touching electrical equipments.
Internal Fuse
The thyristor unit have internal fuse extrarapid at low I²T for the thyristor protection of against the short-circuits.
The Fuses must have I²T 20% less than thyristor’s I²T. The warranty of thyristor is null if no proper fuses are used.

T are multiplied for K value in function of Vac, at
500V K is equal to 0,7 (ex:100000 X 0,7 = 70000).
At 690Vac K is equal to 1.
