Product details

The Schneider Electric A9F04303 is a 3 A, 3-pole miniature circuit breaker from the Acti9 iC60 family, built for distribution panels and branch-circuit protection. At 400 V AC it also carries a 6 kA Icn rating under EN/IEC 60898-1, the domestic standard, so it qualifies for both commercial and industrial specs.

That is a standard 3-pole footprint, so it drops into any 18 mm-per-pole panel layout without surprises. Depth is 78.5 mm, height 91 mm; leaves room for wiring gutters in a typical 200 mm deep enclosure.
