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.
