The MGN60511 is a C60N miniature circuit breaker from Schneider Electric's Multi9 range, built for distribution-level overcurrent protection. It's a single-pole unit with a D-curve trip characteristic, rated 10 A at 50 °C per EN/IEC 60947-2, and carries a 10 kA Icu breaking capacity at 240 V AC phase-to-neutral.
D-curve and selectivity
A standard B-curve would nuisance-trip on the start-up surge; the D-curve holds through the inrush and clears only on a hard fault. For a 10 A unit, that means magnetic trip between roughly 96 A and 144 A. That matters for uptime in distribution boards where a downstream short shouldn't scrap the protective device.
