Product details

The Schneider Electric A9F03450 is an Acti9 iC60N miniature circuit breaker rated 50 A, 4-pole, with a B tripping curve.

Breaking capacity and standards

Rated breaking capacity reaches 36 kA Icu at 12–133 V AC and 20 kA Icu at 220–240 V AC per EN/IEC 60947-2. 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.
