The MGN61882 is a Schneider Electric Multi9 C60H-DC miniature circuit breaker, 2-pole, rated 10 A at 50 °C per EN/IEC 60947-2, with a K-curve trip characteristic. It is built for DC networks — 220 V, 250 V, 440 V, or 500 V DC — and delivers a breaking capacity of 20 kA Icu at 250 V DC. The thermal-magnetic trip unit has a magnetic tripping limit of 12 x In (±20 % DC), so it handles high inrush loads like DC motor drives or solenoids without nuisance trips. The tunnel terminals accept up to 25 mm² rigid stranded (AWG 4) or 16 mm² flexible; torque to 2.5 N·m. IP20 finger-safe front, IP40 inside the modular enclosure. Padlockable toggle provides ON/OFF indication and contact position indication for safe isolation.
Mechanical durability is rated at 20,000 cycles, electrical durability at 3,000 cycles (L/R = 2 ms). Pollution degree 3 per EN 60947-2, tropicalisation class 2 per IEC 60068-2. Relative humidity tolerance: 95 % at 55 °C. The breaker is suitable for isolation — it provides a visible contact gap when toggled OFF.
