Brief introduction
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, fault electrical devices, etc. Automatic control is realized by built-in computer chip. Its operating principle: the detected arc impulse is processed, compared and identified by electronic circuit and MCU. Once fault arc impulse which easily creates fire detected, the output will drive tripping unit to cut off the load power supply, so that the fire is prevented.
Function
AFDD aims to detect hazardous arc impulse which easily creates fire(such as insulation decreasing between lines, 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, t can not only prevent electrical fire, electric shock to human, overload danger, etc, but also be customized with different functions.
Application
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, air plane), especially for anti-fire use in residential house.
