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 I²t 20% less than thyristor’s I
2
t. The warranty of thyristor is null if no proper fuses are used.

T are multiplied for K value in function of Vac, at 690V K is equal to
1,1 (ex:15400 X 1,1 = 16940). At 660Vac K is equal to 1
Fuses replacement:
Open the cover and remove the screws,
then replace it with the correct fuse, use the screws with a proper
suggested torque indicated below
TYPE Screw
Torque Lb-in
(N-m)
60A-210A M6 44.2 (5.0)
300A-800A M8 133.7(15.0)
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.
