characteristic
When a single-phase line experiences overvoltage, the line is cut off, and the single-phase line voltage returns to normal after a delay. The line is automatically reset and connected without manual operation.
When there is a transient or transient voltage in the 2 lines, the protector does not malfunction.
When the voltage of the 3 lines is unstable due to faults such as loose contacts, or when there is a sudden power outage and then a sudden power outage, the protector does not connect the lines.
When the fault voltage of the 4 lines is at its highest, the protector itself will not be damaged.
The protector exhibits inverse time limit action characteristics, with an action time of ≤ 1s.
