The Schneider Electric A9F07432 is an Acti9 iC60H miniature circuit breaker (MCB) rated 32 A with a C-curve magnetic trip at 8 x In ±20 % — meaning it holds through moderate inrush (motor start, capacitor bank) and trips fast on a hard short. Four poles (4P) switch all live conductors, so it suits three-phase plus neutral distribution in a panel. The 15 kA Icn at 400 V AC (EN/IEC 60898-1) and 15 kA Icu at 380–415 V AC (EN/IEC 60947-2) tell you it safely interrupts fault currents up to that level without welding contacts or cascading upstream — sized for commercial and light industrial sub-distribution boards where the prospective short-circuit current is known. The thermal-magnetic trip unit combines a bimetal strip for overload protection and a solenoid for short-circuit — no electronic auxiliary power needed, which keeps the trip curve stable across temperature swings inside a warm enclosure.
Snaps onto a DIN rail (mounting support per). The 72 mm width (9 mm pitches × 8) means it occupies eight modular spaces in a distribution board — plan the rail layout accordingly. Double terminals top and bottom accept 1–35 mm² rigid or 1–25 mm² flexible; strip length 14 mm, tighten to 3.5 N·m. The toggle control provides local on/off switching with a trip indicator (red flag) that shows when the breaker has opened on fault — useful for a technician scanning a row of MCBs to find the tripped circuit without metering each one.
Dual-certified to EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (household / similar) — the same breaker covers both installation standards, which simplifies procurement when a panel must meet both a local residential code and an industrial machinery directive.
