The Schneider Electric C60H3P50AD is a 3-pole C60H miniature circuit breaker from the Multi9 range, rated 50 A at 40 °C with a D trip curve. The D curve's magnetic tripping limit of 10...14 x In means it handles high inrush loads — motor starting, transformer energization, or welding equipment — without nuisance tripping on the magnetic element, while still clearing hard faults. Breaking capacity is 10 kA Icu at 440 V AC (IEC 60947-2), with higher ratings at lower voltages: 30 kA at 230...240 V AC and 25 kA at 125 V DC (2P). For distribution panels feeding motor control centers or general branch circuits, this gives solid fault-clearing headroom.
Fixed mounting, tunnel-type terminals accept up to 35 mm² rigid or 25 mm² flexible wire; strip length 14 mm, torque to 3.5 N·m. The 6-pitch (54 mm wide) footprint fits a standard 3-pole MCB slot.
