The Schneider Electric A9C61440 is a Reflex iC60N integrated control circuit breaker from the Acti9 range — a 40 A, 4-pole unit with a curve B trip characteristic that combines overcurrent protection with remote switching capability in a single DIN-rail package. Rated 40 A with a thermal-magnetic trip unit, it delivers a breaking capacity of 20 kA Icu at 220...240 V AC and 10 kA Icu at 380...415 V AC, both conforming to EN/IEC 60947-2 — enough headroom for most distribution and control panel fault levels. The control circuit accepts multiple voltage options — 230 V AC, 24 V AC, 48 V AC, 24 V DC, or 48 V DC — and supports maintained, impulse, or continuous command signals, so it fits both traditional panel wiring and PLC-driven remote control schemes.
The 4-pole configuration protects all four conductors, making it suitable for three-phase plus neutral distribution or control circuits where full isolation is required. The 35 mm symmetrical DIN rail mounting and fixed mounting mode mean it clips into standard panel profiles without extra hardware, and the 13 x 9 mm pitch (117 mm width) occupies a predictable footprint for panel layout planning.
Designed for distribution and control applications, this integrated control circuit breaker handles both overcurrent protection and remote on/off switching in a single device — reducing component count in panels for lighting control, HVAC, pump stations, and general building services. The remote control by pulse ON/OFF button or continuous command means it can be wired to a PLC output, a pushbutton station, or a building management system for centralized load management.
Integration notes
The 117 mm width (13 x 9 mm pitches) fits standard enclosure rail spacing. Allow clearance above and below for the 84 mm height and 77 mm depth when routing wires. Padlockable in the OFF position (provision for padlocking included) for lockout/tagout compliance during maintenance. The contact position indicator and local signalling LEDs — green for ON, flashing for tripped or ready, red for fault — give clear status at the panel face. Earth-leakage protection requires a separate block (Vigi iC60 or similar), so factor that into the panel layout if ground-fault protection is needed.
