Arc Fault Protection Appliance (AFDD), also known as fault arc breaker, implements the National Standard GB/T31143-2014 "General Requirements for Arc Fault Protection Devices (AFDD)", GB16917 "Household and similar applications with overcurrent protection Residual current operated circuit breaker (RCBO). The fault arc circuit breaker has the functions of overload, short circuit, electric leakage and fault arc detection. It can cut off the circuit power and protect the life and property of the people before the electrical fire occurs. It can be widely used in various electrical circuit systems.
