That dual certification is the compliance gate for panel builders: 60898-1 covers the domestic / commercial MCB application, while 60947-2 covers the industrial circuit-breaker role with higher interrupting ratings (50 kA Icu) and a pollution degree 3 rating, meaning it's verified for conductive-dust environments typical of control panels. The utilisation category is Category A per 60947-2, which means it is not intended for current making and breaking under fault — that is the upstream moulded-case or air breaker's job. ## Panel integration — DIN rail and terminal constraints It occupies 6 x 9 mm pitches (54 mm width) on the rail, which is the standard 3-pole MCB footprint — no surprise for a panel layout. The wire stripping length is 14 mm. IP20 finger protection is provided on the front face, so it is safe for open-panel installation but not for washdown zones. The toggle provides local on/off and trip indication; the unit can be padlocked in the off position for lockout/tagout.","metaTitle":"Schneider Electric A9F44303 iC60N MCB, 3 A C-Curve, 3P, 50 k","metaDescription":"Schneider Electric A9F44303 Acti9 iC60N miniature circuit breaker, 3 A rated, C-curve, 3-pole, 50 kA breaking capacity at 415 V AC.
