Operate time accuracy in definite time mode
2)
+ 4.0% / - 0% of the set value
Operate time accuracy in inverse time mode
2)
+ 8.5% / - 0% of the set value
(at theoretical B in range of 1.1…5.0)
Also note fixed minimum operate time (IDMT) 1 s.
Reset ratio for control operation
Reset ratio for analogue based blockings (except
run back raise voltage blocking)
Typical 0.80 (1.20)
Typical 0.96 (1.04)
1) Default setting values used
2) Voltage before deviation = set Band center voltage.
