Intelligent reclosing power supply protector is an intelligent product developed by using the principle of mechanical automation and the technology of high voltage intelligent reclosing controller. It can solve the problem that the equipment can not automatically resume power supply after power failure due to the switch trip caused by thunderstorm, unstable power grid Impact and man-made transient fault, and provide stable and reliable power supply for the equipment, so as to extend the service life of the electrical equipment, improve the quality of network service, and reduce the cost of network maintenance. The product is suitable for AC 50Hz / 60Hz, rated current in 63A mains line. In case of leakage, over-current, short circuit, over-voltage and under voltage fault, the power supply line can be cut off quickly. After the fault is eliminated, the power supply line can be automatically reclosed and connected without manual closing, so as to ensure the safety and continuity of power supply of electrical equipment and lines. It is suitable for all kinds of electrical equipment in various environments, such as communication base station, repeater station, satellite ground receiving station, microwave transmitting station, video monitoring, safe city, cable TV, digital TV, network switch, optical terminal, meteorological telemetry station, seismic monitoring station, photovoltaic network box, smart home, unattended simple machine room, outdoor integrated cabinet, integrated access special equipment Chassis, confidential outdoor and unattended equipment and other places. This product conforms to gb6829-1995 General requirements for residual current operated protective devices and gb16917.1-2003 residual current operated circuit breakers (RCBOs) with overcurrent protection for household and similar purposes.

Detection Before Closing	The intelligent reclosing power protector detects the line before closing, inputting over-voltage, under-voltage, leakage, over-current overload / short circuit, any fault does not close, preventing the accident from happening before the accident.
Over-Voltage Protection	When the voltage between the zero live line of the input terminal is greater than 275V or the set value, the protector trips to protect.
Under Voltage protection	When the voltage between the zero live line of the input terminal is less than 165V or the set value, this switch trips to protect.
Overcurrent Protection	When the supply current is greater than or equal to 1.15 times the rated current and an overcurrent lasts for more than 3 seconds, the switch trips to protect.
Short Circuit Protection	When the power supply current is 3 times or more of the rated current, the switch will protect in 0.1 seconds and trip and cut off the power supply.
Leakage Protection	When the line exceeds the set leakage or personal electric shock, the auto-reclosing power protector is disconnected within 0.1 seconds, ensuring personal safety.
Neutral Disconnect Protection	After the external neutral wire is loosened or cut off, the protector is opened to protect.
Auto Disconnect When Power Off	When the line is powered off, it will be automatically disconnected, and it will be automatically switched on after detecting that the power supply is normal after re-calling.
Intelligent Leakage Identification	Automatically detect the voltage of the power supply line and the disconnection of the neutral line before closing. If any fault exists, the power supply will be closed.
Automatic Reclosing	After the above faults have tripped, they will automatically re-close after a certain time interval.
Sound And Llight Failure Alarm	When the above protection is disconnected, different indicators are on, indicating the corresponding fault type, and an audible alarm sounds.

(1) Install the protector on the wall or in the main box to avoid direct rain and sunshine.
(2) The protector shall be connected under the circuit breaker or knife switch, the power supply shall be connected with the input end and the load shall be connected with the output end.
(3) If the red indicator light is on 10 seconds after the protector is powered on, it indicates that there is a corresponding fault in the line. After the protector is turned off for 10 seconds, it can be turned on again. If it still cannot be turned on for power transmission, it indicates that the leakage current in the line exceeds the specified value, or the line has over-current and short circuit, all loads shall be turned off, the cause shall be found out immediately, and the power can be turned on only after the fault is eliminated.
(4) The protector can replace the existing leakage switch and circuit breaker. When installing the protector, it cannot be used at the same time with the existing common leakage switch. The installed leakage protection switch shall be removed.
(5) Connect the power supply according to the panel identification of the protector, the power supply line and ground wire of the electrical equipment, and pay special attention that the input and output cannot be connected reversely.

Parameter Setting (Figure 1)

○ Press and hold the "Set / Query" key for 5 seconds to enter the parameter setting interface from the main interface.
○ The overvoltage indicator is on, showing the current overvoltage value (the default value is 275V). Press the "▲/Change" key to adjust the overvoltage value up to 300V, and press the "▼/Silencer" key to adjust the minimum overvoltage value to 250V.
○ Short press the “Set / Query” key, the undervoltage indicator is on, the current undervoltage value is displayed (the default value is 160V), press the “▲/Change” key to adjust the undervoltage value up to 190V, and press the “▼/Silencer” key Adjust the undervoltage value to a minimum of 150V.
