The Schneider Electric A9N1P32DGN is a single-pole miniature circuit-breaker from the Acti9 range, carrying the xC60 device short name. It clips onto a standard 35 mm DIN rail and occupies 18 mm width at 85 mm height and 77.5 mm depth — two 9 mm pitches. Rated 32 A with a D tripping curve, it is built for distribution duty on AC networks at 220…240 V, 50/60 Hz.
Overvoltage category IV and pollution degree 3 mean this breaker is rated for the main distribution board — not just sub-panels — where transient overvoltages are highest and the environment may be conductive or dusty. The thermal-magnetic trip unit provides both overload (thermal bimetal) and short-circuit (magnetic) protection in one compact package. Tropicalisation level 2 per IEC 60068-1 adds mould and corrosion resistance for humid or coastal installations. The IP20 finger-safe terminals protect personnel during panel work.
