Arc Fault Detection Devices reduce the risk of electrical fire
Broken wires, loose connections, crushed cables can all cause hidden arc faults in electrical circuits, which if left undetected, can erupt into flames in just seconds. AFDDs isolate the faulty circuit the moment an arc fault occurs.
Arc faults are one of the main causes of electrical fires
Electrical fires due to arc faults are surprisingly common especially in older homes, causing considerable damage to property, injuries and deaths in Europe each year.
What is an Arc Fault Detection Device?
An AFDD is a circuit breaker that automatically cuts the electricity supply when it detects an arc fault in a circuit. By immediately cutting off the electricity supply, AFDDs prevent arc faults from reaching temperatures where fires can break out.
Do AFDDs meet IEC standards?
Schneider Electric AFDDs comply with IEC 62606, a new international standard covering product safety and performance. In addition, since 2014, the international rules recommend the use of AFDDs to protect against arc faults in final circuit according to the IEC/HD 60364-4-42.
Can other protective devices replace AFDDs?
Compact and easy to install, AFDDs fit into residential and building electrical switchboards, alongside other protective equipment. They cannot be replaced by any other protective device like miniature circuit breakers (MCBs), surge protection devices (SPDs), or residual current devices (RCDs). While these protect against specific electrical hazards, they are not designed to detect arc faults. For example, a smoke alarm is designed to alert occupants to the presence of smoke AFTER a fire has started, whereas AFDDs are designed to PREVENT a fire from starting.
