4.5.1 Short Circuit Protection
For “type 2 coordination”, use fuses for semiconductor protection to protect the TPS from a short circuit.
Fuses for semiconductor protection give excellent results because they have low I²t values and high
interruption ratings.
Recommended fuse selection procedure:
(1) Fuse rated voltage: Choose minimum fuse rated voltage which is above the rated voltage of the
mains.
(2) Fuse rated current: Select a fuse which is 1.6 times the rated TPS current
(3) Fuse I²t: Verify that the I²t value of the fuse is less than or equal to the I²t value of the thyristor in the
TPS as shown in the table below.

Note: In 1000V models semiconductor protection fuses for “type 2 coordination" are built –in.
The fuses listed under “installed fuses” in the table above are recommended, however equivalent fuses from
other manufacturers can be used as well as long as their I

t values are equal or lower to the values mentioned
in parentheses.
4.5.2 Transient Protection
Line transient voltages can cause a malfunction of the TPS and damage to the thyristors. All TPS units
incorporate Metal Oxide Varistors (MOV) to protect from normal line voltage spikes.
When higher transients are expected, additional external protection should be used (consult factory).
