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 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

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.
