Application Scope

A comprehensive intelligent protector integrating overvoltage protection, undervoltage protection, overcurrent protection, and reclosing function, which can instantly disconnect the circuit upon detecting overvoltage, undervoltage, or overcurrent faults in the line, preventing unnecessary damage to electrical equipment. Once the circuit returns to normal, the protector automatically restores the circuit, allowing electrical equipment to operate normally.
This product allows for adjustable overvoltage, undervoltage, overcurrent values, circuit recovery time, and overcurrent protection reset time. Adjustments can be made according to local conditions and electrical usage requirements.

Product Features

1. Single-phase self-restoring reclosing protector, fully compliant with corporate production standards.

2. In the event of overvoltage, undervoltage, or overcurrent faults in the circuit, this product automatically cuts off the circuit; once the line voltage or current returns to normal, it automatically restores power supply after a delay set by the user, without requiring manual operation.

3. The protector does not cause a false operation during instantaneous or transient overvoltage of the circuit.

4. In the event of unstable voltage or sudden power outages followed by power restoration due to certain factors, this product will not immediately reconnect to the power source. The delay time is set by the user according to local conditions.

5. Line voltage should not exceed 330VAC when high, to prevent damage to the product due to excessively high power supply voltage. If there is a specific occasion requiring high power supply, please contact the manufacturer.

Normal operating conditions

The ambient temperature around the product does not exceed +35°C and is not below -10°C.

2. The installation location's altitude does not exceed 2,000 meters.

3. Atmospheric Conditions a. Air relative humidity should not exceed 50% when the surrounding air temperature is +35°C; higher relative humidity is permissible at lower temperatures. b. In the wettest month, the average low temperature is 20°C with an average relative humidity of 90%. c. Condensation on the product surface due to temperature changes has been taken into account. 4. Pollution Grade The pollution grade used for the protector is Grade 3.
