The Schneider Electric A9C63416 is a Reflex iC60N Ti24 integrated control circuit breaker — think of it as a combined remote-controlled switch and MCB in one DIN-rail package. It's part of the Acti9 range, rated at 16 A with a curve D trip characteristic and 4 protected poles. The 'integrated control' part means you can switch the load on and off remotely via a control signal — either a maintained 230 V AC signal, a pulse from an ON/OFF button, or a toggle command. It also accepts low-voltage control at 24 V AC/DC or 48 V AC/DC, which is handy if you're running it from a PLC or a separate control transformer. The magnetic trip threshold on a D-curve is typically 10 to 14 times the rated current, so it won't nuisance-trip on startup but still clears a hard fault.
Breaking capacity is 20 kA Icu at 220–240 V AC and 10 kA Icu at 380–415 V AC per EN/IEC 60947-2. Pollution degree 3 covers conductive dust and humidity. Electrical durability is 50,000 cycles under AC-1 (resistive) load. Mechanical durability matches at 50,000 cycles. That's a lot of remote switching — if you're cycling this thing every hour, it'll last about 5.7 years continuous. For occasional remote disconnect, it's effectively lifetime.
Where you'd use it and how it mounts
It takes up 13 modules of 9 mm pitch (117 mm total width), so plan your DIN rail real estate accordingly. It's fixed mounting only, no plug-in base. That's standard for panel-mounted breakers — it belongs inside an enclosure with at least an IP54 door. The Reflex iC60N is designed for distribution and control applications. Think remote lighting control in a warehouse, motorized valve control in a process line, or as a remotely resettable feeder breaker in a small automation panel. The padlockable OFF position (padlock sold separately) adds a lockout/tagout point for maintenance safety.
A note for the commissioning engineer
The local signalling on this unit is fairly comprehensive: a flashing LED indicates device ready, a steady green LED means the device is ON, a flashing LED signals overheat, a red LED indicates a fault, and a separate flashing LED shows the device has tripped. That's a lot of diagnostic info without needing to open the panel door — useful for a field service tech trying to figure out why a line stopped. Earth-leakage protection is handled by a separate block (Vigi or similar), not built in. If you need RCD functionality, you'll need to add that downstream or order a combined unit. The Reflex iC60N itself is a thermal-magnetic breaker only.
