The Schneider Electric A9C52340 is a Reflex iC60N integrated control circuit breaker from the Acti9 range — a 3-pole, 40 A thermal-magnetic MCB with a C-curve trip characteristic, designed for control and distribution applications on AC networks at 50/60 Hz. It mounts on a 35 mm symmetrical DIN rail, fixed position, and occupies 11 x 9 mm pitches (99 mm width) — standard panel footprint for a 3P device.
Control and signalling
The control circuit accepts multiple voltages: 230 V AC, 24 V AC, 48 V AC, 24 V DC, and 48 V DC — so it works with both AC and DC control systems common in industrial panels. Control is by maintained or impulse signal, with a toggle ON/OFF button and remote pulse capability. Local signalling includes a green LED for ON, red for fault, flashing for trip or overheat — gives a quick visual on the panel door without opening the enclosure. A contact position indicator and padlock provision (OFF position) support lockout/tagout procedures.
Integration notes
IP20 rated per IEC 60529 — suitable for dry indoor enclosures only; not for washdown or outdoor use. Earth-leakage protection requires a separate block (not integrated), so plan for an external RCCB or RCBO if ground-fault protection is needed. Electrical durability is 50,000 cycles at AC-1 (resistive load) — fine for frequent switching in lighting or distribution panels. Mechanical durability matches at 50,000 cycles.
