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.

*
I2T are multiplied for K value in function of Vac at
500V K is equal to 0,7 (ex:15400 X 0,7 = 10780).
At 660Vac K is equal to 1.

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 it is supply, the Thyristor unit is subject to dangerous voltage, don’t open
the Fuse-holder module and don’t touch the electric equipments.
