The Schneider Electric MGN60525 is a C60N miniature circuit breaker from the Multi9 range, a 2-pole D-curve unit rated 25 A at 50 °C per EN/IEC 60947-2. It breaks up to 20 kA at 240 V AC phase-to-phase, 10 kA at 415 V, and 6 kA at 440 V — the Icu figures drop as line voltage climbs, which is typical for this class. The D-curve magnetic trip triggers at 12 x In (±20 %), so it's built for loads with a high inrush, like small transformers or motor starters, where a C-curve would nuisance-trip on startup.
The toggle gives local ON/OFF indication and a contact position indicator confirms the state even if the toggle is forced. Earth-leakage protection requires a separate block (not built in).
