The MGN60870 is a Schneider Electric C60N miniature circuit breaker from the Multi9 range, rated 25 A at 50 °C per EN/IEC 60947-2. The C-curve means magnetic tripping occurs between 5 and 10 times rated current (8.5 x In ±20 % per the spec), so it's sized for general-purpose distribution loads like lighting, socket circuits, and small motor feeders where inrush isn't extreme. The 1-pole (1P) configuration protects one phase; the neutral is switched separately if needed. Breaking capacity is 10 kA Icu at 240 V AC phase-to-neutral, with a service breaking capacity (Ics) of 7.5 kA (75 %) at the same voltage — meaning after clearing a fault at that level the breaker remains functional, not just safe. The part is rated Category A per EN/IEC 60947-2, which covers general distribution without specific short-time delay requirements.
Width is 18 mm (2 x 9 mm pitches), so it occupies one module position. Depth is 73 mm, height 81 mm. IP20 rated, so it's for dry indoor enclosures only. Pollution degree 3 per EN/IEC 60947-2 means it's suitable for environments with conductive or dry non-conductive pollution — typical for most industrial control panels.
