Application Summary AI generated
This standard specifies the general requirements, performance criteria, and testing methods for arc fault detection devices (AFDDs) used in low-voltage electrical installations. It is applied in residential, commercial, and industrial settings to detect dangerous series or parallel arc faults in circuits, helping to prevent electrical fires by automatically disconnecting power when an arc is identified. The standard is primarily used by manufacturers, electrical engineers, and safety inspectors for product design, certification, and compliance verification in China.
