It is a thermal-magnetic trip unit, clip-mounted on DIN rail, and carries a current lifecycle status. ## Breaking capacity and dual-standard rating The 10 kA Icu rating under EN/IEC 60947-2 is the ultimate short-circuit capacity the breaker can interrupt once and remain functional; the 6 kA Icn under EN/IEC 60898-1 is the service capacity for repeated faults in a residential or light commercial distribution board. For a 16 A, 3P MCB in a 400 V AC panel, 10 kA Icu gives solid headroom above typical 6 kA or 10 kA prospective fault levels — it won't be the weak link in a selectivity study. ## C-curve trip characteristic The C curve has a magnetic trip threshold of 5 to 10 times In (80 to 160 A for this 16 A unit) per EN/IEC 60898-1, and 8 x In ±20 % per EN/IEC 60947-2. That's the standard choice for mixed resistive-inductive loads — lighting, small motors, general-purpose socket circuits — where inrush is moderate and nuisance tripping on start-up is unlikely. Clip-on mounting to DIN rail, 6 module pitches (54 mm wide), tunnel terminals top and bottom accepting 1 to 16 mm² rigid or 1 to 10 mm² flexible. Tightening torque 2 N·m, strip length 14 mm. IP20 finger-safe terminals, IP40 in the modular enclosure — standard for a distribution board. The locking option via padlocking device suits lockout/tagout procedures.","metaTitle":"Schneider Electric A9P54316 Acti9 iC40N MCB, 16 A, 3P, C Cur","metaDescription":"Schneider Electric A9P54316 Acti9 iC40N miniature circuit breaker, 16 A, 3-pole, C curve, 10 kA Icu at 400 V AC.
