Low-voltage switchgear and controlgear - Active arc-fault mitigation systems. Arc quenching devices1 Scope This part of IEC 60947 covers low voltage arc quenching devices, hereinafter referred to as AQDs, which are intended to eliminate arc faults in low voltage assemblies (typically low voltage switchgear and controlgear assemblies in accordance with the IEC 61439 series), by creating a lower impedance current path, to cause the arcing current to transfer to the new current path. This new current path is maintained until a short circuit protection
