The Schneider Electric A9K24213 is an Acti9 iK60N miniature circuit breaker — a 2-pole, 13 A thermal-magnetic MCB with a C-curve trip characteristic, built for AC distribution panels. Rated 13 A at 30 °C, it carries a 6 kA breaking capacity at 400 V AC (Icn per EN/IEC 60898-1), which means it can safely interrupt a fault current up to 6,000 A on a 400 V line without welding its contacts or failing catastrophically — enough for most commercial and light industrial sub-distribution boards where the upstream transformer limits fault current. If you're feeding a bunch of LED drivers or a small contactor coil, this curve handles the brief surge without nuisance tripping.
Depth is 78.5 mm, height 85 mm. That 78.5 mm depth matters when you're laying out a shallow wall-mount enclosure; check your gutter clearance before you commit the BOM. That's a solid grip on a 4 mm² feed for a 13 A circuit — no need to pigtail down to a smaller terminal. IP20 finger-safe front; once it's in the panel the enclosure provides the environmental seal. Padlocking provision lets you lock it off for lockout/tagout without removing the breaker.
