Automatic reclosing power leakage protectorSuitable for AC 50Hz/60Hz, rated current up to 63A lines, as protection against overvoltage, low voltage, overcurrent/short circuit, leakage, etc. for lines and equipment. Suitable for electrical equipment in various environments, such as communication base stations, repeaters, video surveillance, safe cities, cable TV, digital TV, network switches, optical transceivers, meteorological telemetry stations, earthquake monitoring stations, photovoltaic grid cages, smart homes, and other places.
Function:

○ Pre closing detection: The automatic reclosing power protector checks the circuit before closing, detecting input overvoltage, undervoltage, leakage, short circuit, and any faults that exist will not close, preventing accidents from happening before they occur.

○ Overvoltage protection: When the voltage between the neutral and live wires of the input terminal is greater than 280V or the set value, this switch trips for protection.

○ Undervoltage protection: When the voltage between the neutral and live wires at the input terminal is less than 140V or the set value, this switch trips for protection.

○ Overcurrent protection: When the supply current is greater than or equal to the rated current 1 When there is an overcurrent lasting for more than 3 seconds at a rate of 15 times, this switch will trip for protection.

○ Short circuit protection: When the supply current is greater than or equal to 3 times the rated current, this switch will activate within 0.1 seconds and trip to cut off the power supply.

○ Leakage protection: In the event of a leakage or personal electric shock exceeding the set limit in the circuit, the automatic reclosing power protection device will operate at 0 Disconnect within 1 second to ensure personal safety.

○ Neutral wire disconnection protection: When the external neutral wire becomes loose or cut, and the three-phase voltage becomes unbalanced to a certain value, the protector will open for protection.

○ Automatic disconnection when power is cut off: The circuit will automatically disconnect when power is cut off, and when power is restored and normal supply is detected, it will automatically close and turn on the power.

Intelligent leakage detection: Automatically detect the voltage of the power supply line, the disconnection of the neutral line, etc. before closing. If any faults exist, the power supply will be refused to close.

○ Automatic reclosing: After the above-mentioned fault trips, it will automatically reclose and power on after a certain time interval.

○ Automatically save trip information: Automatically save various information during the trip, including trip time, trip type (reason), voltage, current, leakage current, etc. Provide a basis for fault analysis.

○ Sound and light fault alarm: When the above protection is disconnected, different indicator lights will light up to indicate the corresponding fault type, and the sound will beep.

○ Remote monitoring: With RS485 interface, it is convenient to connect with existing system equipment and achieve remote monitoring. Real time viewing of voltage, current, leakage current, number of trips, trip type (reason), total number of alarms, switch status, and other data can be achieved through software.
