Breaking capacity is the headline: 36 kA Icu at 12–60 V AC, 20 kA at 100–133 V AC, and 10 kA at 220–240 V AC per EN/IEC 60947-2, plus 6 kA Icn at 230 V per EN/IEC 60898-1. Thermal-magnetic trip unit, 1P+N configuration (neutral switched, left position), pollution degree 3, overvoltage category IV — this is a main-panel or sub-distribution board MCB, not a final-circuit gadget. The IP20 finger-safe terminals accept 1–25 mm² rigid or 1–16 mm² flexible, double-terminated top and bottom, with 2 N.m torque and 14 mm strip length.
No direct replacement or successor is listed because none is needed — the iC60N platform is the current generation. If you are retrofitting an older Multi9 or C60 series panel, the A9F04606 is the direct functional equivalent with the same 36 mm width per pole and DIN-rail footprint.
The toggle actuator and trip indicator give local status without opening the panel door. Neutral is on the left — wire accordingly if the panel layout has a fixed busbar orientation. Tropicalisation class 2 per IEC 60068-1 and 95% RH at 55 °C rating make it suitable for non-condensing humid environments like pump rooms or outdoor-rated enclosures, though the IP20 body itself is not washdown-rated.
