Afci (arc fault circuit interrputer)

AFDD, short for the arc fault detection device, is a new kind of electric line protection device. Its main functions are detecting and distinguishing dangerous grounding arc fault, arc fault in parallel and in series, and driving timely to motivate the current breaker to avoid electrical fire. It adopts the embedded system digital circuit control and the original arc feature recognition algorithm. It is small in size but strong in functions, and being integrated with leak current protection function, it can realize the automatic monitoring and protection of arc fault and leak current, thus it can effectively guarantee the safety of the low voltage distributed power line, electric equipment and personnel.

Arc Fault Circuit Breaker
12 Advantages 

Be equipped with power leakage protecting function which greatly enhances the reliability of the safe use of electricity.The technology of electromagnetic mechanism has been improved and handled in terms of material, technique and electronic circuit to avoid the electromagnet getting heat or excess temperatures after long time work and to considerably lower the working temperature of the electromagnet, thus its service life is increased.Be applicable to all kinds of loads and has high stability.The maximum working current of the circuit can reach 63A.High-performance MCU is used in system design to realize digital control.Electromagnetic tripping mechanism is specially used, which enormously enhances the accuracy of over-current protection.When arc fault happens, the inner MCU will carry out multiple judgments. Only when all the features are tallied will the tripping motion be performed.This product has a wide range of application, including households, enterprises, hospitals, schools and science and research units.Integration: the short circuit protection, earth leakage protection and arc protection are integrated in one.Stability: its detection capability will not be affected by the shield of inhibitive load or EMI load.Multiple domain detection: time domain and frequency domain.Flexible installation: plug-in type and screw type.
