The thermal-magnetic trip unit handles overloads and short circuits, with a magnetic tripping limit of 8 x In ±20%. At 440 V AC the Icu drops to 25 kA, and under EN/IEC 60898-1 the Icn is 6 kA at 400 V AC. It meets both the industrial (60947-2) and residential/light commercial (60898-1) standards, so it's suitable for either duty. ## Integration details The 4-pole version (4P) occupies 8 x 9 mm pitches on the DIN rail — 72 mm wide. IP20 finger-safe protection is standard for enclosed panels.","metaTitle":"Schneider Electric A9F04403 Acti9 iC60 MCB, 3 A C-Curve, 4P","metaDescription":"Schneider Electric A9F04403 Acti9 iC60 miniature circuit breaker, 3 A rated, C-curve, 4 poles, 50 kA breaking capacity at 220-240 V AC.
