The Schneider Electric A9KF71416 is an Acti9 K60 miniature circuit-breaker rated 16 A with a C curve, 4 protected poles, and a breaking capacity of 10 kA Icn at 415 V AC (EN/IEC 60898-1). It is a thermal-magnetic MCB for distribution in 50/60 Hz AC networks, mounted on a DIN rail in a panel enclosure.
The 16 A rated current (In) sets the continuous load the breaker carries without tripping. The C curve (magnetic trip 5–10 × In) means it tolerates moderate inrush — typical for motor starters, small transformers, and lighting banks — without nuisance trips, while still clearing short-circuits fast enough for cable protection. DIN-rail mounting (72 mm wide, 8 x 9 mm pitches) and tunnel terminals accepting 1–25 mm² rigid or 1–16 mm² flexible wire make it a standard panel fit. IP20 finger-safe terminals are fine for enclosed panels; no washdown rating, so keep it inside the cabinet.
