AFDD, or Arc Fault Detection Device, is an electrical safety device designed to detect and prevent electrical arc faults in a circuit. These arc faults can occur when the electrical current passes through a nonconductive medium, such as air, and ionizes gases, creating temperatures that can exceed 6,000°C. These hot temperatures can potentially start a fire.

AFDDs work by monitoring the electrical waveform and identifying any abnormal patterns that may indicate an arc fault. When an arc fault is detected, the device will interrupt the circuit, preventing potential fire hazards. Some AFDDs are combined with residual current circuit breakers (RCCB) and miniature circuit breakers (MCB) to provide comprehensive protection against several types of electrical faults.
