8. Fuses and fuseholder

8.1 Fuses and Fuse Code
CD3000M unit must be protected by fuses against short circuit selecting the proper I²t that must
be lower than thyristor one. The same caution must be taken if Circuit Breaker is used. Remember
that is very difficult to protect the thyristor if this choice is done.
WARNING!! Equipment short circuit protected by Semiconductor Fuse type
with proper I
