TH-PV relay is suitable for power systems with three-phase voltage AC380V, providing protection for
1.over voltage,
2.under voltage,
3.phase failure,
4.three-phase imbalance,
5.phase sequence situations in power lines.
| Protection function | Model code TH-PV |
|---|---|
Over voltage protection range (AC) | 385V-460V |
Under voltage protection range (AC) | 300V-375V |
Over voltage and under voltage protection time | 1-30S |
Three phase imbalance protection range | 5%~49% |
Time range of three-phase imbalance protection | 1~25S |
Phase failure protection action time | ≤2S |
Phase sequence protection | Instantaneous (after confirming the phase sequence, if the phase sequence error occurs when starting the load again, the load cannot be started) |
