The Schneider Electric A9C63410 is an Acti9 Reflex iC60N Ti24 integrated control circuit breaker — a 4-pole, 10 A thermal-magnetic MCB with a D curve that also packs remote switching, local signalling, and padlocking into a single DIN-rail module. It's not just a breaker; it's a control element that replaces a separate contactor + MCB pair in distribution and control panels.
Breaking capacity and selectivity — what the ratings actually mean
This Reflex iC60N carries a 20 kA Icu at 220–240 V AC and 10 kA Icu at 380–415 V AC, per EN/IEC 60947-2. At 240 V, 20 kA puts it in the 'high fault' tier for a 10 A breaker; you can coordinate it downstream of a 25 kA or 36 kA upstream device without worrying about cascading failure. The 'N' breaking capacity code means it's the standard (not 'H' high or 'L' limited) variant in the iC60 family.
Integration — what it connects to and how it mounts
At 117 mm wide (13 x 9 mm pitch modules), it occupies the same footprint as a 4P MCB plus a separate contactor would, but in one unit. Control voltage options cover 24 V DC, 48 V DC, 24 V AC, 48 V AC, and 230 V AC — pick the one your PLC or pushbutton station already runs. The remote control accepts pulse ON/OFF, continuous command, or toggle signals, so it works with a simple maintained switch or a momentary pushbutton. Earth-leakage protection is handled by a separate Vigi block downstream — this unit doesn't include RCD functionality.
What the local signalling tells you
The Reflex iC60N has a multi-colour LED on the front: green for ON, flashing green for ready, flashing for tripped, red for fault, and flashing for overheat. That's enough to walk a field tech through a fault without opening the panel door — green = normal, flashing = thermal trip or overload, red = short-circuit or internal fault. The padlock provision (OFF position only) lets you lock it out for maintenance without removing the breaker.
