The Schneider Electric A9C63316 is a Reflex iC60N Ti24 integrated control circuit breaker from the Acti9 range — a 3-pole, 16 A thermal-magnetic MCB with a D curve, designed for distribution and control applications on AC networks at 50/60 Hz. Breaking capacity is 20 kA Icu at 220…240 V AC and 10 kA Icu at 380…415 V AC, both per EN/IEC 60947-2 — enough for most industrial panel secondary distribution.
Control and integration
This isn't just a breaker — it's an integrated control device with an ON/OFF button and remote control capability via pulse or continuous command, using a separate control voltage (230 V AC, 24 V AC/DC, or 48 V AC/DC). Mounts on a 35 mm symmetrical DIN rail (fixed mounting), taking 11 × 9 mm pitches of panel space — 99 mm wide, 84 mm high, 77 mm deep. IP20 rated per IEC 60529, so it's for dry indoor enclosures only; pollution degree 3 suits industrial environments with conductive pollution.
Earth-leakage protection is handled by a separate block (not built in), so if you need RCD functionality, plan for an add-on Vigi module.
