Arc Fault Detection Devices AFDD

The arc fault detection devices AFDD (hereinafter referred to as AFDD) can effectively detect the fault arc in the access line, including the fault parallel arc and the fault series arc. When the fault arc causing fire is detected in the line, it can perform the function of disconnection and power-off to realize the purpose of early warning of fire. The arc fault dectection device is applicable to the electrical lines of 10kW and below in industrial and civil buildings. The length of the protection line should not be greater than 100m. The products comply with GB/t31143-2014 IEC62602 standard and can be applied to nursing homes, schools, commercial buildings, hotels, factories, warehouses, libraries, offices, family houses, and entertainment places.
