Arc-fault detection in a 1P+N package
The Schneider Electric A9TDE3616 is an Acti9 iCV40 ARC arc-fault detection circuit breaker (AFDD) rated 16 A, Curve B, 1P+N, with a 6 kA Icn breaking capacity per EN/IEC 61009-2-1 and a 10 kA Icu per EN/IEC 60947-2. The integrated arc-fault detection meets EN/IEC 62606, meaning it discriminates series and parallel arcing from normal load current — a key requirement for fire-prevention circuits in residential and commercial final distribution.
The 36 mm width (4 x 9 mm pitches) and 73 mm depth fit standard distribution boards; the tunnel terminals accept 1 to 16 mm² rigid or 1 to 10 mm² flexible conductors, stripped 14 mm, torqued to 2 N·m.
