The A9N3P04CIN is a 4 A, 3-pole miniature circuit-breaker from the Acti9 xC60 family. The 10 kA breaking capacity at 380–415 V AC (15 kA at 100–125 V DC) is rated per IS/IEC 60947-2 — that's the industrial standard for selectivity, not the residential EN 60898.
Integration into a DIN-rail enclosure
The 54 mm width (6 x 9 mm pitches) occupies three pole positions on the rail. IP20 finger-safe protection is standard for enclosed panels.
