The use of over voltage protection device
1 single phase line occurs when the line is cut off line, single-phase line voltage resume normal after the delay of automatic reset circuit, without manual operation.
2 line transient or transient over-voltage, the protector does not produce false action.
3 line due to the failure of the contact point and other voltage instability, or sudden power failure and sudden call, the protector is not connected to the line.
4 line fault voltage is the highest, the protector itself will not be damaged.
5 a protector tripping characteristics, operation time is less than 1s.
6 voltage protection range: 40A the following 0 ~ 50/60A,:0 450V ~ 600V.
7 withstand impact voltage: 4kV (meet the safety standards of class III).
8 protector has a two - color light emitting diode indicator working condition, green - normal voltage indicator, red - over - voltage or delay indicator.
9 the shape of a modular design, rail mounted.
10 terminal capacity: 25 square mm and the following insulated conductor
