Mode of Operation
DUA01 and PUA01 monitor
both AC and DC over voltage.
When connected with MI or
MP
(using the 0.4 - 4 V
they can monitor 1-phase or
3-phase AC currents up to
500 A.
Example 1
(connection between termi-
nals Z1, Y1 or 8, 9 - latch
function enabled)
The relay operates and latch-
es
when the measured value
exceeds the set level. Pro-
vided that the voltage has
dropped min. 4% below the
set point (see hysteresis),
the relay releases when the
interconnection between ter-
minals Z1, Y1 or 8, 9 is inter-
rupted or the power supply
is interrupted as well.

Example 2 (MI CT)
(no connection between ter-
minals Z1, Y1 or 8, 9)
The relay operates when the
current flowing through the
CT exceeds the set level. It
releases when the current
drops min. 4% below the set
level
when power supply is inter-
rupted.
Example 3 (MP CT)
(no connection between ter-
minals Z1, Y1 or 8, 9 - latch
function disabled)
The relay operates when the
maximum
through the CT exceeds the
set level. It releases when
the maximum current drops
min. 4% below the set level
(see hysteresis) or when
power supply is interrupted.
