The MGN25147 is a 4-pole C60H miniature circuit breaker from the Schneider Electric Multi9 range, rated 25 A with a D tripping curve. It's built for distribution panels where high inrush currents — motor starts, transformer energisation, or rectifier loads — demand a curve that holds through the surge.
Breaking capacity and what it means on your panel
The MGN25147 delivers 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 service breaking capacity Ics is 50% of those figures: 15 kA at 240 V, 7.5 kA at 415 V, and 5 kA at 440 V. Ics matters because it's the rating that tells you whether the breaker can be reused after a fault without replacement.
At 72 mm wide and 8 x 9 mm pitches, it occupies four module spaces on the rail. IP20 finger protection means it's safe for open-panel mounting inside a locked cabinet; no washdown rating here.
