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.","metaTitle":"Schneider A9F68340 Acti9 iT60 MCB, 40A C-Curve 3P 36kA","metaDescription":"Schneider A9F68340 Acti9 iT60 miniature circuit breaker, 40A rated, curve C, 3-pole, 36kA breaking capacity at 133V AC.
