Automatic Reclosing Protector for Over/Under Voltage & Over Current

Short Description:

It is a comprehensive intelligent protector integrating over-voltage protection, under-voltage protection, and over-current protection. When faults such as over-voltage, under-voltage, or over-current occur in the circuit, this product can cut off the power supply instantly to prevent electrical equipment from being burned out. Once the circuit returns to normal, the protector will automatically restore power supply.

The over-voltage value, under-voltage value, and over-current value of this product can all be set manually, and the corresponding parameters can be adjusted according to local actual conditions. It is widely used in scenarios such as households, shopping malls, schools, and factories.

Product Features

1. A new generation of self resetting overvoltage and undervoltage protector designed and produced entirely based on the enterprise standard Q/SUZ1GQ001-2012.
2. When a single-phase line experiences undervoltage or overcurrent faults, the line is cut off, and the single-phase line voltage returns to normal after a delay, automatically resetting and connecting the line without the need for manual operation.
3. When there is a transient or transient overvoltage on the line, the protection will not cause misoperation.
4. When the voltage of the circuit is unstable or suddenly disconnected and then suddenly reconnected due to faults such as loose contacts, the protector will not connect to the circuit.
5. When the line fault voltage is at its highest, the protector itself will not be damaged.
