The Schneider Electric MGN61835 is a 1-pole DC miniature circuit-breaker from the Multi9 C60H-DC series, rated 25 A at 50 °C with a C-curve trip characteristic (8.5 x In magnetic trip limit). It breaks 20 kA at 110 V DC, 10 kA at 220 V DC, and 6 kA at 250 V DC per EN/IEC 60947-2 — the 110 V figure is the one that governs most telecom and solar combiner box faults. It clips onto DIN rail, occupies 2 x 9 mm pitches (18 mm wide), and is suitable for isolation with a visible contact position indicator.
This is a DC distribution breaker for telecom rectifiers, solar string combiners, battery banks, and DC motor control panels. The clip-on DIN rail mount and 18 mm width let it slot into standard enclosure rails alongside other Multi9 devices. The padlockable toggle and ON/OFF indicator make it lockout/tagout ready for maintenance isolation.
