The Schneider Electric MGN60634 is a C60H miniature circuit breaker from the Multi9 range, rated 1 A with a C-curve trip characteristic and three protected poles. It carries a 30 kA Icu breaking capacity at 240 V AC phase-to-phase, certified to EN/IEC 60947-2 — the standard for industrial circuit-breaker performance and coordination. The C-curve (magnetic trip at 8.5 x In ±20%) means it handles moderate inrush from small motor or transformer loads without nuisance tripping, while still clearing short circuits fast enough to protect downstream wiring.
At 125 V DC the Ics is 40 kA at 100%, which is unusually high for a 1 A MCB and makes this unit a strong candidate for DC distribution panels where fault currents can spike.
Snaps onto 35 mm symmetrical DIN rail (EN/IEC 60947-2 mounting support). Occupies 6 x 9 mm pitches (54 mm wide) — standard 3-pole footprint. Tunnel terminals accept 1–25 mm² rigid or flexible conductors; tighten to 2 N·m.
