DIA01, PIA01
Mode of Operation
DIA01 and PIA01 monitor
both AC and DC over current
through an internal shunt.
They can monitor AC cur-
rents up to 6000 A when
connected to a suitable cur-
rent transformer.
Example 1
(connection between termi-
nals Z1, Y1 or 8, 9 - latch
function enabled)
The relay operates and latch-
es in operating position
when the measured value
exceeds the set level. Pro-
vided that the current has
dropped min. 4% below the
set point (see hysteresis) the
relay releases when the inter-
connection between termi-
nals Z1, Y1 or 8, 9 is inter-
rupted or the power supply
is interrupted as well.
Example 2 (Stardard CT)
(no connection between ter-
minals Z1, Y1 or 8, 9 - latch
function disabled)
The relay operates when the
current flowing through the
transformer exceeds the set
level. It releases when the
current drops min. 4% below
the set level (see hysteresis)
or when the power supply is
interrupted.
