The Schneider Electric A9F04704 is an Acti9 iC60N miniature circuit-breaker rated 4 A with a C-curve, 3P+N poles, and a thermal-magnetic trip unit. The 50 kA Icu at 415 V AC (EN/IEC 60947-2) and 6 kA Icn (EN/IEC 60898-1) breaking capacities mean it handles high fault currents in commercial and industrial panels — the Icu rating governs the maximum short-circuit it can interrupt without damage, while the Icn rating covers the standard domestic/commercial duty cycle.
The 72 mm width (8 x 9 mm pitches) and 78.5 mm depth fit standard distribution boards. Double terminals accept 1–25 mm² rigid or 1–16 mm² flexible cable; strip length 14 mm, tightening torque 2 N.m. IP20 finger-safe terminals. Neutral is on the left. The toggle control and trip indicator provide local status. Separate earth-leakage protection block can be added alongside.
Rated for isolation (EN/IEC 60898-1 and 60947-2). Overvoltage category IV, pollution degree 3. Electrical durability 10,000 cycles, mechanical 20,000 cycles. Tropicalisation class 2 (IEC 60068-1). Limitation class 3. Operating frequency 50/60 Hz. Ambient humidity 95% at 55 °C.
