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.

I t are multiplied for K value in function of Vac at
500V K is equal to 0,7 (ex:20400 X 0,7 = 14280).
At 660Vsc K is equal to 1.
