The Schneider Electric A9N18413 is an Acti9 C120H miniature circuit breaker (MCB) rated 80 A at 30 °C with a B-curve trip characteristic (magnetic tripping between 3 and 5 x In). The headline breaking capacity is 15 kA Icn at 400 V AC 50/60 Hz per EN/IEC 60898-1, with an Icu of 10 kA at 440 V AC and 30 kA at 220–240 V AC per EN/IEC 60947-2. This dual-standard rating means the breaker is certified for both residential (60898-1) and industrial (60947-2) fault-clearing requirements, giving the specifying engineer flexibility in panel design without swapping hardware.
Mounts via clip-on to 35 mm DIN rail — standard for panel and enclosure integration. The 54 mm width (9 mm pitch × 6) occupies six modular spaces, which is typical for a 2-pole 80 A MCB in the Acti9 range. Tunnel-type terminals accept 1–50 mm² rigid or 1.5–35 mm² flexible conductors; wire strip length is 15 mm, tightening torque 3.5 N·m. IP20 finger-safe protection is suitable for enclosed panels.
Dual-certified to EN/IEC 60898-1 (MCB standard for household and similar installations) and EN/IEC 60947-2 (low-voltage switchgear and controlgear standard for industrial application). This dual certification is the key differentiator: the same breaker satisfies both a domestic distribution board spec and an industrial panel SCCR study. Electrical durability is 5,000 cycles (IEC 60947-2), mechanical durability 20,000 cycles. Earth-leakage protection requires a separate block (not integrated).
