ABSTRACT:
The present invention relates to an arc fault detection apparatus using a microcomputer, which divides current paths into a low current path and a high current path depending on the intensity of load current using a source voltage that is applied to a lead wire and determines whether an arc fault signal exists, and which presets a circuit breaking time against the generation of an arc, corresponding to the magnitude of a load, and immediately breaks a circuit if a corresponding arc fault signal is detected within the preset circuit breaking time.
