Abstract: Arc fault is always to be the reason why the electrical machine fires. A new type of intelligent control device—arc fault circuit interruputer was introduced. On the basis of studying the occurrence of arc fault and the corresponding collection of the arc, a composite criterion of arc fault was brought forward. Aiming at protecting the lowvoltage distribution system，the hardware structure and software processes of circuit device were designed, and new features to protect were added. The results indicate that the successful development of the device has opened up a new area for low voltage electrical protection.
Key words: electrical fires; arc fault; circuit devices; microcontrol unit
