| Characteristic | Value |
|---|---|
| Operation accuracy | Depending on the frequency of the measured current: f n ±2 Hz |
| ±1.5% of the set value or ±0.002 × I n | |
| Operate time accuracy | ±1.0% of the set value or ±20 ms |
| Reset time 1 | Typically 40 ms |
| Retardation time | <20 ms |
1 Trip pulse time defines the minimum pulse length
