People who have used over voltage and under voltage protection devices know their benefits. But do you know what are the unique advantages of the voltage protector? The following are the unique advantages of over voltage and under voltage protection devices:

1. When the single-phase line is under voltage, the line will be cut off, the voltage of the single-phase line will be restored to normal, and the line will be reset automatically after the delay, without manual operation.

2. When the line appears transient or transient over-voltage, the protector does not generate misoperation.

3. The line due to improper contact, such as voltage failure occurs, or sudden power failure, and suddenly call, the protector is not connected to the line.

4. The line fault voltage is the highest, the protector itself will not be damaged.

5. The protector is characterized by an inverse time limit, operation time is less than 1s.

6. Voltage protection range: 40A below 0 ~ 450V, 50/60A:0 to 600V.

7. Withstand shock voltage: 4kV (accord with safety standard of class III Electric Appliance).

8. The protector has two color led to indicate the working state, green normal voltage indication, red over or under voltage or delay indication.

9. Modular design of shape, rail mounting.

10. Wiring capacity: insulated wire of 25 mm2 and less
