The Schneider Electric A9C66216 is a Reflex iC60H Ti24 integrated control circuit breaker — a thermal-magnetic MCB with a built-in remote control module, rated 16 A, 2 poles, curve D, from the Acti9 range. The 30 kA breaking capacity at 230 V AC (15 kA at 415 V) per EN/IEC 60947-2 means it can safely interrupt high fault currents without upstream cascading — a key spec for panel SCCR compliance.
Control and integration
The Ti24 control module accepts multiple signal types: maintained very low voltage, impulse, or maintained 230 V AC, 24 V AC/DC, or 48 V AC/DC — so the same part works with a remote pushbutton, PLC digital output, or building management contact. Local signalling via a flashing/green/red LED indicates device ready, tripped, overheat, or ON — useful for quick fault isolation without a meter.
Environmental and durability
Electrical durability of 50,000 cycles in AC-1 (resistive load) and matching mechanical durability — aligns with typical panel life for a controlled distribution circuit. IP20 finger-safe terminals per IEC 60529; earth-leakage protection requires a separate Vigi block (not integrated).
