DC-rated miniature circuit breaker for distribution panels
The Schneider Electric MGN61826 is a Multi9 C60H-DC miniature circuit breaker, 1-pole, rated 3 A at 50 °C per EN/IEC 60947-2. It's a thermal-magnetic trip unit with a C-curve — magnetic tripping limit at 8.5 x In ±20 % DC — sized for DC distribution circuits where moderate inrush (lighting, small DC drives, control transformers) won't nuisance-trip the instantaneous element. Breaking capacity is 20 kA Icu at 110 V DC, 10 kA at 220 V DC, and 6 kA at 250 V DC, all conforming to EN/IEC 60947-2. Rated operational voltage is 250 V DC, with 110 V DC and 220 V DC also listed.
Height 81 mm, depth 73 mm. Tunnel-type terminals top and bottom accept 1…25 mm² rigid stranded (AWG 18…4), or 1…16 mm² flexible with ferrule. Wire stripping length 14 mm, tightening torque 2.5 N·m. The terminal can also take up to three 1 mm² flexible stranded cables in one clamp — useful for daisy-chaining the outgoing feed to a downstream load. IP20 finger-safe per IEC 60529; IP40 in a modular enclosure.
