Rated 10 kA Icn at 415 V AC 50/60 Hz per EN/IEC 60898-1, this MCB can safely interrupt fault currents up to that level on a 400 V three-phase network. Fixed mounting on DIN rail, 72 mm wide (8 × 9 mm pitches), 81 mm tall, 70 mm deep. The IP20 finger-safe enclosure suits enclosed distribution boards — not washdown locations. ## Standards and durability Certified to EN/IEC 60898-1, limitation class 3, pollution degree 2, overvoltage category II. Rated for 10,000 electrical cycles and 20,000 mechanical cycles — typical for a panelboard MCB that sees occasional switching.","metaTitle":"Schneider Electric A9KF71450BQ Acti9 K60 50A 4P C-Curve MCB","metaDescription":"Schneider Electric A9KF71450BQ Acti9 K60 miniature circuit breaker, 50A rated, 4-pole, C curve, 10 kA breaking capacity at 415 V AC, EN/IEC 60898-1.
