At 400 V AC, the Icn per EN/IEC 60898-1 is 6 kA. This dual-standard rating (60947-2 for industrial and 60898-1 for residential/commercial) means the breaker can serve in either context — the 60947-2 figures govern fault clearance in industrial panels where higher prospective fault currents are expected. The 4-pole version isolates all live conductors, and the unit is marked as suitable for isolation per both standards. Snap-on DIN rail mounting, 72 mm wide (8 x 9 mm pitches). Tightening torque 3.5 N.m. The IP20 finger-safe front is standard for enclosed panel installation.","metaTitle":"Schneider Electric A9F03450 Acti9 iC60N MCB, 50 A, 4P, B Cur","metaDescription":"Schneider Electric A9F03450 Acti9 iC60N miniature circuit breaker, 50 A, 4-pole, B curve, 36 kA breaking capacity.
