Product Introduction

The automatic reclosing protector is suitable for AC 50HZ and rated 220V power lines. When overvoltage, undervoltage, or overcurrent faults occur in the line, this product can instantly cut off the power supply to avoid unnecessary damage to electrical equipment.When the line returns to normal, the protector can automatically restore power supply. The overvoltage cut-off value, undervoltage cut-off value, overcurrent protection value, leakage protection value, etc. of this product can be set by oneself, and the corresponding parameters can be adjusted according to the local actual situation.Suitable for electrical equipment in various environments, such as homes, schools, enterprises, municipal engineering, streetlights, farms, rental houses, water pumps, underfloor heating, water heaters, etc.

PRODUCT FUNCTION

1. This product has an LCD backlight display, which displays real-time parameters such as grid voltage, current, leakage, and electricity. The product uses a high-precision metering chip specifically designed for State Grid Corporation of China, with 24 bit ADC numerical sampling accuracy.

2. The on-site setting protection functions include overvoltage, undervoltage, overcurrent, leakage, delay, etc. The battery can be accumulated and reset to zero. It also has the function of one click reset of factory settings in the setting menu.

3. This product does not support automatic closing function after leakage protection. When the product experiences leakage protection disconnection (screen displays OFF), please immediately check and eliminate the leakage fault of the circuit or equipment, and then manually close it before normal use.

4. Short press the setting button on the product to quickly view the setting parameters, and long press the setting button for three seconds to enter the setting program.
