Note 1 The setting ranges of the relay nominal voltage U
n
are dependent on the version (to be selected on purchase), with reference voltages U
R
100 V
or 400 V.
Note 2 When the rated voltage of the electricity network divided by √ 3 corresponds to the value of rated primary voltage of the sensors (20000 / √ 3),
then the nominal voltage of the relay must be adjusted to Un = 100 V (default setting).
Note 3 The 26 element is available when the MPT module is connect on Thybus and enabled
Note 4 The mathematical formula for INVERSE curve is: t= (0.75 ∙ t
U
<
inv
) / [1 - (U/U<
inv
)]
t = operating time (in seconds)
t
U
<
inv
= operating time setting (in seconds)
U = input voltage
U<
inv
= threshold setting
