The neutral sits on the left side of the unit. That matters when you're wiring a single-phase final subcircuit where you need to isolate both conductors but only protect the line. That's a compact footprint for a 63 A 1P+N unit; you can fit about 8 of these per foot of DIN rail in a distribution board. The tunnel-type terminals accept up to 35 mm² rigid or 25 mm² flexible, with a recommended tightening torque of 3.5 N.m and a strip length of 14 mm. Terminal capacity that generous for the 63 A rating means you can land larger incoming cables without needing an adapter or reducing the conductor. It's certified to EN/IEC 60898-1, which is the harmonized European standard for MCBs used in household and similar installations. The limitation class 3 rating means it limits the let-through energy (I²t) to a level that protects downstream equipment better than a class 1 or 2 device — useful when you're coordinating with sensitive loads or trying to achieve selectivity with an upstream breaker. ## Where it's used and how it fits This MCB goes into a DIN-rail enclosure — typically a consumer unit, distribution board, or sub-distribution panel in a commercial building, small workshop, or residential installation. It's a distribution device (per the application field), meaning it's the downstream protection for lighting, socket circuits, and small loads, not the main incoming breaker. Rated insulation voltage is 440 V AC, so it's fine on a 230/400 V three-phase system when used on a single-phase leg. The IP20 protection means it's touch-safe but not splash-proof — install it inside a panel, not out in the weather.","metaTitle":"Schneider Electric A9K24663 Acti9 iK60N MCB, C-Curve 63 A, 6","metaDescription":"Schneider Electric A9K24663 Acti9 iK60N miniature circuit breaker, 1P+N, 63 A, C-curve, 6 kA breaking capacity.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time."},{"question":"What is the breaking capacity of the A9K24663?","answer":"The A9K24663 has a rated breaking capacity of 6000 A Icn at 230 V AC 50/60 Hz conforming to EN/IEC 60898-1. That's the maximum fault current it can safely interrupt under standard test conditions."},{"question":"What does the C-curve mean on this MCB?","answer":"The C-curve means the magnetic trip operates at 5 to 10 times the rated current — 315 A to 630 A for this 63 A unit. It's the standard choice for general distribution circuits feeding lighting, sockets, and small motor loads where you don't expect high inrush currents."},{"question":"What compliance documentation is available for the A9K24663?","answer":"The A9K24663 is certified to EN/IEC 60898-1, which is the harmonized European standard for miniature circuit breakers.
