The AFDD fault arc protector, hereinafter referred to as the protector, effectively detects the fault arc in the access line, including the fault parallel arc and the fault series arc. When it detects that there is a fault arc that causes a fire in the line, the outlet power-off function can be carried out to achieve the purpose of warning of the occurrence of a fire.

The AFDD fault arc protector is suitable for electrical lines of 10KW and below in industrial and civil buildings, and the length of the protection line should not be more than 100 meters.

The product follows the GB/T 31143-2014 IEC62602 standard, which canIt is suitable for nursing homes, schools, commercial buildings, hotels, factories, warehouses, libraries, offices, family residences,and entertainment venues, etc.

Operating instructions

1.Operating indicator (green), when the product is powered on and running normally, the RUN indicator light is on, indicating that the faulty arc function is turned on.

2.Leakage indicator (red), when the product is separated due to leakage failure, the next time the gate is closed, the leakage indicator light will flash the alarm, and the alarm will be automatically lifted after 60 seconds.

3.Arc indicator (yellow), when the product is separated due to an arc failure, the next time the gate is closed, the arc indicator light flashes to alarm, and the alarm will be automatically lifted after 60 seconds.

4.Product reset. When the product is disconnected due to an arc or leakage failure, the R button will pop up, and you need to press it to close the gate.
