| Characteristic | Value |
|---|---|
| Operation accuracy |
Depending on the frequency of the measured current and voltage: fn ±2 Hz |

| Start time 1 2 | Typically 26 ms |
| Reset time | Typically 40 ms |
| Reset ratio | Typically 0.96 |
| Operate time accuracy in definite time mode | ±1.0% of the set value or ±20 ms |
| Operate time accuracy in inverse time mode | ±5.0% of the set value or ±20 ms |
| Suppression of harmonics | -50 dB at f = n × fn, where n = 2, 3, 4, 5,… |
1 Measurement mode = default, current before fault = 0.0 × In, fn = 50 Hz, fault current in one phase with nominal frequency injected from random phase angle, results based on statistical distribution of 1000 measurements
2 Includes the delay of the signal output contact
