The Schneider Electric A9C52363 is a Reflex iC60N integrated control circuit breaker — a thermal-magnetic MCB with a built-in remote control function, rated 63 A, 3 poles, curve C. It combines overcurrent protection with the ability to switch the load on and off via a control signal, eliminating the need for a separate contactor in distribution and control applications.
Rated 20 kA Icu at 220–240 V AC and 10 kA Icu at 380–415 V AC per EN/IEC 60947-2. That N-class breaking capacity means it coordinates well downstream of a higher-rated upstream device — the site electrical engineer can build a selective trip scheme without oversizing every branch breaker. The 63 A rating and 3-pole configuration cover a standard three-phase subfeed or a large single-phase load.
Control and signalling
Control voltage options are 230 V AC, 24 V AC, 48 V AC, 24 V DC, or 48 V DC — the same unit accepts maintained or impulse commands. The local signalling LEDs (green for ON, red for fault, flashing for tripped or ready) give the field service tech immediate status without a meter. The 77 mm depth and 99 mm width fit standard distribution board cutouts — 11 modules of 9 mm pitch.
The paperwork is straightforward — RoHS and REACH declarations are standard for the Acti9 family, and the IEC 60947-2 certification covers most global acceptance. No special customs classification issues; it falls under standard HS code for circuit breakers.
