(6) 161 to 164 Leakage detection setting 【With leakage measurement】
The rated sensitivity current value of leakage measurement, a detection factor, the circuit configuration at the
case of 3-phase 3-wire, and setting of ZCT to be used are performed.

◆ 161 Leakage detection rated sensitivity current value
Set the rated sensitivity current value of current leakage.
Setting value can be selected from 0.03A, 0.05A, 0.1A, 0.2A, 0.4A, 0.8A.
Selection by
＋
and
－
, set value is updated by
SET
.
Default setting：0.1A
◆ 162 Leakage detection factor change
Measurement of current leakage and detection factor can be selected
from Io and Igr.
Selection by
＋
and
－
, set value is updated by
SET
.
However, a current input product constitutes Io fixation and cannot carry
out Igr detection.
Default setting：Io
<Caution> Please apply a voltage input, in case you measure and detect
Igr. In case the voltage input is not applied, measurement or
detection of Igr cannot be performed correctly.
◆ 163 Leakage detect-circuitry change
The circuit configuration of the current-leakage detection in 3-phase 3-wire can be selected from 1-phase earthing,
1-phase earthing (negative phase sequence), and non-earthing.
Selection by
＋
and
－
, set value is updated by
SET
. Default setting：A (1 phase earthing)
<Caution> If actual connection is different from this setting, a current leakage Igr cannot measure or detect
correctly. Setting of "1-phase earthing (negative phase sequence)" is setting for making Igr measure
and detect correctly, in case a circuit is a negative phase sequence. In the case of the right usual
phase sequence, it is not necessary to make it this setting.
◆ 164 Use ZCT selection
ZCT used by current-leakage measurement can be selected.
Selection by
＋
and
－
, set value is updated by
SET
.
Default setting：0(TYPE 0)
<Caution> If ZCT which you actually use is different from this setting, the error of current leakages Io and
Igr will become large. In case you use ZCT(s) other than our company recommendation goods, please
consult in advance.
TYPE 0：Our company recommendation product (Standard).
TYPE 1：Except our company recommendation product.
