The Schneider A9F68340 is a 40 A, C-curve, 3-pole miniature circuit breaker from the Acti9 iT60 series, rated for both AC and DC networks. At 400 V AC, the Icn under EN/IEC 60898-1 is 10 kA, which is the standard domestic/commercial rating. It's a distribution breaker, not a motor-protective device; the thermal-magnetic trip unit handles overloads and short-circuits in one package.
Snaps onto DIN rail (EN/IEC 60715) and occupies 6 x 9 mm pitches — 54 mm wide for the 3P block. The removable comb busbar installs across the top or bottom terminals, so you can gang-feed multiple breakers in a distribution board without individual bridging. Terminals accept 1–35 mm² rigid or 1–25 mm² flexible, stripped to 14 mm, torqued to 3.5 N·m. IP20 B finger-safe on the front face; suitable for dry indoor enclosures, not washdown.
Marked as current production (L* lifecycle stage). No NRND or phase-out flag. This is the standard Acti9 iT60N — widely specified across European and Middle East distribution boards.
