The Schneider Electric A9C52225 is a Reflex iC60N integrated control circuit breaker — a 2-pole, 25 A thermal-magnetic MCB with curve C trip characteristic, designed for control and distribution circuits in Acti9 panels. It combines overcurrent protection with local and remote switching capability, accepting control voltages of 230 V AC, 24 V AC, 48 V AC, 24 V DC, or 48 V DC via maintained or impulse signals. Rated breaking capacity reaches 20 kA Icu at 220–240 V AC and 10 kA Icu at 380–415 V AC, per EN/IEC 60947-2 — sufficient for most commercial and light industrial panelboards where fault levels stay within that range. IP20 finger protection covers the terminals per IEC 60529.
No substitute is needed; the Reflex iC60N series remains a standard catalog offering in the Acti9 range.
At 81 mm wide (9 module pitches), the breaker occupies a fixed position on the DIN rail — plan for that footprint in your panel layout. The toggle ON/OFF button and LED local signalling (green ON, red fault, flashing for overheat/trip/ready) give clear status at the panel door without additional indicators. Earth-leakage protection requires a separate Vigi block — not integrated. The control circuit voltage must match your system: 230 V AC is the default, but 24 V AC/DC and 48 V AC/DC options are available on the same unit. Verify the control signal type (maintained or impulse) before wiring.
