Internal Fuse
The thyristor unit have internal fuse extrarapid at low I
2
T for the thyristor protection of against the short-circuits.
The Fuses must have I
2
T 20% less than thyristor’s I
2
T. The warranty of thyristor is null if no proper fuses are used.
Remove cover, remove screws and fuses.

T are multiplied for K value in function of Vac at 500V K is equal to 0,7
(ex:480.000 X 0,7 = 336.000). At 660 Vac K is equal to 1.
