The C60H3P50AB is a 3-pole miniature circuit breaker from the Schneider Electric Multi9 C60H series, rated 50 A at 30 °C with a B tripping curve (3–5 × In magnetic trip). Breaking capacity varies by voltage: 30 kA Icu at 230–240 V AC, 15 kA at 400–415 V AC, and 10 kA at 440 V AC, all per IEC 60947-2. Rated operational voltage is 440 V AC, insulation voltage 500 V AC. The 3 protected poles handle three-phase distribution (, L2, L3) with a separate earth-leakage block if needed. Isolation capability is confirmed per IEC 60947-2 — the toggle provides visible ON/OFF indication and a contact position indicator.
Width is 54 mm (6 × 9 mm pitches), depth 73 mm, height 81 mm — occupies 3 standard module spaces. Tunnel-type terminals accept up to 35 mm² rigid or 25 mm² flexible cable; strip length 14 mm, tightening torque 3.5 N·m. Limitation class 3 per IEC 60947-2 limits let-through energy, helping downstream coordination.
