The MGN60880 is a C60N miniature circuit breaker from the Multi9 range, 2-pole, C-curve, rated 10 A at 50 °C per EN/IEC 60947-2. The C-curve magnetic trip is 8.5 x In ±20 %, meaning it holds through moderate inrush (lighting, small transformers) but trips fast on hard shorts. Breaking capacity is 20 kA Icu at 240 V AC phase-to-phase, 10 kA at 415 V, and 6 kA at 440 V — the 20 kA figure is the one that governs most panelboard fault-current ratings; the 415 V and 440 V numbers matter only if the line-to-line voltage actually sits at those levels. The 2 protected poles mean both poles have thermal-magnetic trip elements; it isolates both line and neutral in single-phase DC or two legs of a DC system.
Snaps onto 35 mm symmetrical DIN rail, fixed mounting mode. IP20 finger-safe terminals, tunnel type accepting 1…25 mm² rigid or flexible (with or without ferrule). Tightening torque 2 N·m on the power circuit; strip length 14 mm. Comb busbar and distribution block compatible top or bottom, which simplifies daisy-chaining in multi-pole panels.
Ambient operating range -30…70 °C, storage -40…80 °C. Electrical durability 10,000 cycles, mechanical 20,000 cycles. Earth-leakage protection via separate block (not integral).
