AFDD (arc fault detection device) is a new electrical anti-fire equipment. It could avoid various of fires caused by short circuit, circuit aging, heavy load, poor contact, electric failure, etc. Automatic control is realized by built-in computer chip. Its operating principle: when arc impulse is processed, compared and identified by electronic circuit and MCU. Once fault arc impulse which easily creates fire is detected, the output will drive the tripping unit to cut off the load power supply, to prevent the fire accident.
AFDD aims to detect hazardous arc impulse which easily creates fire (such as insulation decreasing between lines, over-load, short circuit, poor contact of connector, arc caused by house electrical apparatus fault), then it triggers tripping unit to cut off the power supply to prevent electrical fire. AFDD is used together with leakage circuit breaker, low voltage circuit breaker (overcurrent protection) to build a multi function electrical protective device. As a true intelligent low voltage electrical apparatus, it can not only prevent electrical fire, electric shock to human, overload danger, etc, but also be customized with different functions.
As per IEC62606, these different ratings available: 10A, 16A, 20A, 32A, 40A, 63A, usually used in residential houses as a terminal protective device. The applications of AFDD are wide. In theory, it can be used to avoid fire wherever there is electricity, such as in residential house, office building, hospital, shopping mall, supermarket, factory, vehicle (auto, train, vessel, airplane), especially for anti-fire used in residential house.
