The Schneider Electric MGN61849 is a Multi9 C60H-DC miniature circuit breaker designed for DC network protection. It is a 2-pole unit rated at 13 A at 50 °C with a C trip curve, meaning the magnetic trip threshold is set at 8.5 x In ±20% for DC applications — a deliberate choice to handle the inrush of DC loads like battery banks, DC drives, or telecom rectifiers without nuisance tripping. Rated to EN/IEC 60947-2, it carries a breaking capacity of 20 kA Icu at 220 V DC, 20 kA at 250 V DC, 10 kA at 440 V DC, and 6 kA at 500 V DC. Rated insulation voltage (Ui) is 500 V DC, and the rated operational voltages (Ue) cover 220 V DC, 250 V DC, 440 V DC, and 500 V DC — so it fits common DC bus voltages in industrial and utility-scale solar installations.
Clip-on mounting to a DIN rail, 36 mm wide (4 x 9 mm pitches), 81 mm tall, 73 mm deep. The 2-pole body takes up two module spaces on the rail. Strip length is 14 mm; torque to 2.5 N.m. IP20 finger protection on the terminals, IP40 on the modular enclosure — standard for enclosed distribution boards. Padlockable handle and a clear ON/OFF indicator on the toggle. The contact position indicator confirms the state even if the toggle is forced — useful for lockout/tagout procedures on DC circuits where arc flash risks are higher than AC.
The Multi9 C60H-DC series is a well-established Schneider Electric line for DC branch-circuit protection. For a replacement or second-source check, the key specs to match are the 2-pole DC rating, curve C, 13 A, and the 20 kA breaking capacity at 220 V DC. No direct pin-compatible alternative from another brand carries the same EN/IEC 60947-2 DC ratings without a footprint change.
