The A9F08202 is a 2 A rated, D-curve miniature circuit breaker from Schneider Electric's Acti9 iC60H series. The 2 A rating is the continuous thermal current; the thermal-magnetic trip unit protects the downstream conductors and equipment from sustained overloads and short circuits. Breaking capacity is the headline number for this part: 70 kA Icu at 415 V AC (per EN/IEC 60947-2), with an Icn of 10 kA at 400 V (per EN/IEC 60898-1). The 10 kA Icn is the service breaking capacity under the domestic-standard 60898-1 test sequence; the 60947-2 rating governs industrial distribution.
Snap-on DIN rail mounting, 36 mm wide (4× 9 mm pitches), 91 mm tall, 78.5 mm deep. Two-pole configuration (2P) with protected poles on both paths. IP20 finger-safe terminals — suitable for enclosed panel installation, not for wet or washdown environments.
