Protection function:
1.Current instantaneous trip protection (Tripping operation)
2.Time delay current instantaneous trip protection (Tripping operation)
3.Over current protection (Tripping operation)
4.Inverse time over-current protection (general/ special/extreme; You could choose one of them or choose nothing)
5.Overload Protection（Alarm/ Tripping operation)
6.Zero sequence current instantaneous trip protection (Tripping operation)
7.Zero sequence time delay current instantaneous trip protection (Tripping operation)
8.Zero Sequence definite time over-current protection. (Tripping operation)
9.Zero-Sequence Inverse time Over current Protection (general/ special/extreme; you could choose one of them or choose nothing)
10.Zero-Sequence Over-Current Protection (Alarm/ Tripping operation)
11.Over voltage protection (Tripping operation)
12.Low voltage protection (Tripping operation)
13.Under-frequency load shedding (Tripping operation)
14.Three-phase Automatic reclosure (No test)
15.PT line-break (Alarm)
16.PT no-voltage protection
17.Control loop break (Alarm)
Explanation: Within the conditions, the protection function can be increased to meet the needs of the field.
