The Schneider Electric MGN60902 is a C60N miniature circuit-breaker from the Multi9 range — a 4-pole, C-curve unit rated 2 A at 50 °C (EN/IEC 60947-2). The C-curve magnetic trip fires at 8.5 x In (±20 %), which means it tolerates motor inrush or capacitor charging surges better than a B-curve, but still clears fast enough for general branch-circuit protection.
Snaps onto 35 mm symmetrical DIN rail. Takes 8 module pitches at 9 mm each — that is 72 mm wide, 81 mm tall, 73 mm deep. IP20 finger-safe front, pollution degree 3 rated, so it is fine inside a standard enclosed panel.
