The MGN60876 is a Schneider Electric C60N miniature circuit-breaker (MCB) from the Multi9 range — a 2-pole, 2 A rated, C-curve unit built to EN/IEC 60947-2. It's a distribution-grade device (Category A) with thermal-magnetic trip technology, meaning it handles both overload and short-circuit protection in a single package. The 20 kA Icu at 240 V AC (phase-to-phase) is its maximum interrupting capacity under fault; the 10 kA at 415 V AC and 6 kA at 440 V AC tell you how that capacity derates as line voltage climbs — useful when you're dropping this into a panel fed from a 400 V three-phase corner-grounded delta or a 240 V split-phase service. At 2 A rated, this is a branch-circuit protector for a low-current load, not a main feeder. Mounts on a standard 35 mm symmetrical DIN rail (fixed position), occupies 4 x 9 mm pitches (36 mm wide), and the tunnel-type terminals accept up to 25 mm² rigid or flexible conductors.
The MGN60876 carries three Icu ratings depending on voltage: 20 kA at 240 V AC, 10 kA at 415 V AC, and 6 kA at 440 V AC. The Ics (service breaking capacity) is 75 % of those values — 15 kA, 7.5 kA, and 4.5 kA respectively. That 75 % ratio tells you the breaker is rated to clear a fault at the Ics level and still be usable afterward (no immediate replacement required), which is typical for EN/IEC 60947-2 devices.
Integration notes for a panel refit or new build
The 36 mm width (4 modules) is standard for a 2-pole MCB; plan your rail fill accordingly. The IP20 finger-safe terminals are fine for enclosed panels but not for exposed live-front installations. Earth-leakage protection requires a separate block (not integrated). The breaker provides isolation capability (suitability for isolation: Yes per EN/IEC 60947-2) and has a visible contact-position indicator, so it doubles as a service disconnect for the downstream circuit.
