DC-rated miniature circuit breaker for distribution panels
The Schneider Electric MGN61824 is a Multi9 C60H-DC miniature circuit breaker rated 1 A at 50 °C per EN/IEC 60947-2, with a C-curve (magnetic trip at 8.5 x In ±20% DC) and a single protected pole. Breaking capacity reaches 20 kA Icu at 110 V DC, 10 kA at 220 V DC, and 6 kA at 250 V DC — enough to clear high-fault DC supplies common in telecom, UPS, and industrial control panels.
The C-curve (8.5 x In magnetic trip) means it tolerates moderate inrush — typical for resistive loads and small DC power supplies — without nuisance tripping, but still clears short circuits fast.
Clip-on mounting to a standard DIN rail (35 mm). Occupies 2 x 9 mm pitches (18 mm wide), so it fits a single modular slot in a distribution board. Height 81 mm, depth 73 mm — check enclosure depth clearance. Two cables per terminal up to 10 mm². Tightening torque 2.5 N·m. Strip length 14 mm.
