The A9F68316 is a 16 A, 3-pole miniature circuit breaker from Schneider Electric's Acti9 iT60 range, with a C curve (magnetic trip at 8 × In ±20 %). Breaking capacity is dual-rated: 10 kA Icn at 400 V AC per EN/IEC 60898-1 (the household-standard rating), and 10 kA Icu at 380–415 V AC per EN/IEC 60947-2 (the industrial-standard rating).
At 54 mm wide (6 × 9 mm pitches), it occupies three modular spaces — the standard width for a 3-pole MCB. Removable comb busbar installed means it's ready for daisy-chaining line-side feeds across a row of breakers without extra wiring. Tropicalisation class 2 per EN/IEC 60068-2-78 means it withstands 95 % relative humidity — relevant for coastal or unconditioned plant rooms.
No official successor or direct cross-reference exists because it's the active model. If you're maintaining an older panel that used the previous-generation Multi9 or C60 range, the Acti9 iT60 is the direct functional replacement — same footprint, same curve, same breaking capacity class.
