The Schneider Electric A9F56110 is a 1-pole Acti9 IKQ miniature circuit breaker (MCB) rated 10 A with a B tripping curve, designed for AC networks at 240 V and 50/60 Hz.
Rated breaking capacity (Icn) is 10,000 A at 240 V AC per EN 60898-1; the service breaking capacity (Ics) is 7,500 A at the same voltage. That Ics figure matters for selectivity coordination downstream — if you're feeding this breaker from a larger upstream device, the 7.5 kA Ics tells you how much fault current it can clear repeatedly without degrading the unit. The limitation class is 3 per EN 60898-1, meaning it limits let-through energy on a high fault — helps protect downstream wiring and connected equipment.
Depth is 78.5 mm, height 85 mm. That's a standard MCB footprint — fits any Acti9 distribution board or generic enclosure. Terminals accept 1–25 mm² rigid or 1–16 mm² flexible on the bottom connection; strip length is 14 mm, torque to 2 N·m. Padlockable toggle for lockout/tagout.
Rated insulation voltage 440 V AC. Electrical durability 10,000 cycles, mechanical 20,000 cycles.
