The Schneider Electric A9F68432 is a 4-pole miniature circuit-breaker from the Acti9 iT60 range, rated 32 A with a C-curve trip characteristic. It is a thermal-magnetic MCB for distribution duty, meaning it protects branch circuits against overloads and short-circuits in AC/DC networks up to 500 V insulation voltage. Breaking capacity is the headline: 36 kA Icu at 12–133 V AC, 20 kA at 220–240 V, 10 kA at 380–415 V, and 6 kA at 440 V. At 400 V it also carries a 10 kA Icn rating under EN/IEC 60898-1, which is the standard for household-type MCBs. Rated for isolation and carries a contact-position indicator plus a trip indicator — both visible through the transparent toggle so a technician can confirm the breaker is open without touching live parts. Pollution degree 3 means it tolerates conductive dust and condensation typical of industrial panels, not just clean residential environments.
Where it fits in a panel
Width is 72 mm, which is 8 modules of 9 mm pitch — standard DIN-rail footprint for a 4P breaker. Terminals accept 1–35 mm² rigid or 1–25 mm² flexible; strip length 14 mm, torque to 3.5 N.m. IP20 B finger protection suits enclosed panels; not rated for washdown.
