The Schneider Electric MGN60530 is a C60N miniature circuit breaker from the Multi9 range — a 3-pole, 1 A rated device with a D curve, built to EN/IEC 60947-2 for distribution duty. It breaks 20 kA Icu at 240 V AC phase-to-phase, 10 kA at 415 V, and 6 kA at 440 V, so it handles high inrush loads like motor circuits or transformer primaries where the D curve's 12 x In magnetic trip (+/- 20%) avoids nuisance trips on startup.
IP20 finger-safe for panel interiors.
The 1 A rating at 50 °C (EN/IEC 60947-2) governs continuous load — this breaker protects a 1 A branch, not a motor starter. The D curve's 12 x In magnetic trip (12 A nominal, +/- 20%) means it tolerates short-duration inrush without tripping, making it a fit for control transformers, solenoid banks, or small motor loads where a C curve would nuisance-trip. Service breaking capacity (Ics) is 75% of Icu: 15 kA at 240 V, 7.5 kA at 415 V, 4.5 kA at 440 V — enough for most industrial panel fault levels. Electrical durability is 10,000 cycles; mechanical, 20,000 cycles.
