DC-rated miniature circuit breaker for distribution panels
The MGN61886 is a Schneider Electric Multi9 C60H-DC miniature circuit breaker built for DC distribution. It's a 2-pole unit rated 25 A at 50°C with a K-curve trip characteristic — magnetic tripping at 12 x In ±20% DC. The real value here is the DC breaking capacity: 20 kA Icu at 250 V DC, 20 kA at 220 V DC, 10 kA at 440 V DC, and 6 kA at 500 V DC, all per EN/IEC 60947-2. That means it handles fault currents on DC bus systems up to 500 V, with the highest interruption rating at the more common 220–250 V DC levels.
The 2-pole configuration breaks both lines on a DC circuit, which is standard for ungrounded DC systems. The 500 V DC insulation voltage (Ui) confirms it's rated for the full voltage range, not just the lower end.
Height is 81 mm, depth 73 mm — fits standard distribution board cutouts. IP20 finger-safe terminals, IP40 in the modular enclosure. Tightening torque is 2.5 N.m. Padlockable for lockout/tagout. ON/OFF indicator on the toggle. Pollution degree 3 (industrial environment) per EN 60947-2.
