Reset time of DT
(vi)
In the DT characteristic, the reset time is designed to be instant.
Summary of EF operation
(vii)
Table 2.2-3 shows a summary for EF operation. Note that DEF will be set unconditionally in
IEC-NI, VI, EI and UK-LTI characteristics (†).

Threshold level for operation
2.2.3
The value of threshold current at which the EF (I
setting; the setting [EF1] is provided for both the IDMT and the DT characteristic. Note that
the settings of the threshold levels are allowed to have distinct values in the respective EF
elements. A rating current for the input is defined either 1A or 5A using System parameter
settings. (For more information about the rated current, see Chapter
Rated Frequency and Rated current
Reset Ratio
2.2.4
The ratio of the threshold current for pick-up to reset is applied using a setting; for example,
the ratio for the EF1 element is set using the setting [EF1-DPR]. The reset ratios for the other
EF elements are also provided.
