The Schneider Electric A9F03610 is an Acti9 iC60N miniature circuit breaker — 1P+N, 10 A rated, B-curve, thermal-magnetic trip. It's a current-production distribution breaker (lifecycle stage: current) built for DIN-rail panels where you need a switched neutral and a single protected pole.
This breaker carries a 36 kA Icu at 12-60 V AC (EN/IEC 60947-2), 20 kA at 100-133 V, and 10 kA at 220-240 V. Under the residential-standard EN/IEC 60898-1 it's rated 6000 A Icn at 230 V. The dual-standard rating (60947-2 for industrial, 60898-1 for domestic) gives you flexibility in specification: you can use it in a distribution board or an industrial sub-panel.
Trip curve and coordination
B-curve means magnetic trip at 4 x In (40 A, +/-20%). For motor or drive circuits you'd typically step to C or D curve, but for distribution duty this holds selectivity well with upstream C-curve breakers. The thermal-magnetic trip unit gives you inverse-time overload protection (thermal) plus instantaneous short-circuit (magnetic).
Height is 91 mm, depth 78.5 mm — check your gland plate clearance if you're fitting a deep enclosure. Terminals accept 1-25 mm² rigid or 1-16 mm² flexible, double-terminal top and bottom for daisy-chaining. IP20 finger-safe, pollution degree 3 (conductive pollution environment — typical for industrial panels not sealed from the floor).
