The Schneider Electric MGN25120 is a C60H miniature circuit breaker from the Multi9 range, rated 32 A at 50 °C per EN/IEC 60947-2 with a D trip curve.
Breaking capacity and duty
Breaking capacity reaches 30 kA Icu at 240 V AC phase-to-phase, 15 kA at 415 V, and 10 kA at 440 V — all per EN/IEC 60947-2. The rated service breaking capacity (Ics) is 50 % of Icu at each voltage level, so after clearing a fault at 15 kA at 240 V the breaker remains usable, not just safe. That matters for panel builders who want to avoid replacing a breaker after a single fault event.
Snaps onto a 35 mm symmetrical DIN rail, fixed mounting, 2-pole width of 36 mm (4 x 9 mm pitches). Depth is 73 mm, height 81 mm. Tunnel terminals accept 1.5…35 mm² flexible or rigid wire; strip length 14 mm, torque to 3.5 N·m. IP20 finger-safe front. The compact 36 mm footprint leaves room alongside other Multi9 devices in a distribution board.
