It is designed for DC network distribution and mounts via clip-on onto a DIN rail, occupying 2 x 9 mm pitches (18 mm wide). Breaking capacity is rated per EN/IEC 60947-2: 20 kA Icu at 110 V DC, 10 kA Icu at 220 V DC, and 6 kA Icu at 250 V DC. This makes it suitable for DC distribution applications where high fault currents are possible, such as in industrial control panels or telecom power plants. The 1-pole configuration protects a single DC line, with the neutral or return path handled separately. ## Integration notes The 18 mm width (2 modules) fits standard enclosure spacing. IP20 finger protection on the front; IP40 within a modular enclosure. The toggle switch provides local ON/OFF indication, and the unit is padlockable for lockout/tagout procedures. Rated insulation voltage (Ui) 500 V DC. Pollution degree 3 per EN 60947-2.","metaTitle":"Schneider Multi9 C60H-DC MGN61838 MCB, 40 A 1P C-curve DC","metaDescription":"Schneider Electric MGN61838 Multi9 C60H-DC miniature circuit breaker, 40 A rated current, 1-pole, C-curve, 20 kA breaking capacity at 110 V DC.
