The Schneider Electric A9F03204 is an Acti9 iC60N miniature circuit breaker rated 4 A, curve B, 2-pole, with a breaking capacity of 50 kA Icu at 415 V AC.
Rated at 50 kA Icu across 12–415 V AC (50/60 Hz) per EN/IEC 60947-2, and 10 kA Icn at 400 V per EN/IEC 60898-1. That 50 kA figure means it safely interrupts high fault currents typical in industrial panel secondary distribution — no cascading upstream breakers needed on most sub-circuits. The dual standard certification (60947-2 for industrial, 60898-1 for residential/commercial) gives flexibility in specifying across different installation codes.
Occupies 4 x 9 mm pitches (36 mm width) on DIN rail, with a depth of 78.5 mm and height of 91 mm.
