The A9F68216 is a 2-pole Acti9 iT60 miniature circuit breaker rated 16 A with a C curve — magnetic trip at 8 x In ±20 %, so it holds moderate inrush from motor starters or small transformers without nuisance tripping, while still clearing a hard short fast enough for downstream coordination. Breaking capacity is the headline: 36 kA Icu at 12–133 V AC, 20 kA at 220–240 V, and 10 kA Icu at 380–415 V — plus 6 kA Icu at 440 V — all per EN/IEC 60947-2. For distribution duty under EN/IEC 60898-1 it carries 10 kA Icn at 400 V. That dual rating means it can serve either industrial feeder panels (60947-2) or commercial final circuits (60898-1) without swapping the part. Pollution degree 3 means it holds up in dirty or humid environments — the tropicalisation rating (2 conforming to EN/IEC 60068-2-78) backs that for 95 % RH. The removable comb busbar is already installed — wire up single terminals top or bottom, 1–25 mm² rigid or 1–16 mm² flexible, strip 14 mm, torque to 2 N·m.
Dual-certified to EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (household / commercial). Suitability for isolation is confirmed under both standards. IP20 B finger protection on the front face.
