The Schneider Electric C60H2P50AB is a 2-pole miniature circuit breaker from the Multi9 C60H range, rated 50 A with a B-curve trip characteristic.
The C60H2P50AB carries a 10 kA Icn rating at 230/400 V AC per EN 60898 — that's the standard for domestic and commercial final circuits. Under IEC 60947-2, the Icu (ultimate breaking capacity) goes higher: 15 kA at 400–415 V AC, 25 kA at 125 V DC (2-pole series trip), and 30 kA at 230–240 V AC. The Ics (service breaking capacity) is 7.5 kA at 230/400 V AC per EN 60898, meaning it can clear a fault at that level and still be used again afterward. For a 50 A feeder, that gives decent selectivity with upstream devices rated 25 kA or higher — common in a sub-distribution board fed from a 100 A or 160 A MCCB.
The 2-pole body takes 4 modules of 9 mm pitch — 36 mm wide total, 81 mm tall, 73 mm deep. That's a standard footprint for a 2-pole MCB; it fits any DIN-rail enclosure or distribution board without surprises.
