Application WB600 series (ARC FAULT DETECTION DEVICES,or AFDD) is new smart protection device by using digital electronics to analyse the waveform of A.C. circuit, to continuously monitors the circuit for different variations including the duration of an arc and the waveform. Once the device detects an irregular fault the device trips and disconnects the circuit, reducing the chance of it over heating and potentially causing an electrical fire. Under the standards of IEC/EN-62606,GB/T31143-2014,IEC/EN61009,GB14048.2, and combined with arc fault detection, short circuit, overload, over-voltage and earth leakage detection, the device is used for electrical fire prevention or monitoring occasions, and also for infrequent switching of the circuit under normal circumstances.To ensure commitment to safety and quality, the Combined AFDD & RCBO has been certified by UTV,CE and CCC.
