It is designed for DC network distribution and clips onto a DIN rail for panel integration. The C curve (magnetic tripping limit 8.5 x In ±20 % DC) means it tolerates moderate inrush currents — suitable for motor and transformer loads on DC circuits, not for purely resistive loads where a B curve would be tighter. Breaking capacity of 20 kA Icu at 110 V DC, 10 kA at 220 V DC, and 6 kA at 250 V DC tells you the maximum fault current the breaker can safely interrupt at each voltage. For a 110 V DC bus, this handles most panel-level faults without cascading upstream. The rated insulation voltage of 500 V DC and operational voltage up to 250 V DC confirm it is built for DC rail voltages common in telecom, solar combiner boxes, and industrial control panels. Thermal-magnetic trip technology combines a bimetal strip for overload protection and a solenoid for short-circuit response. The 8.5 x In magnetic threshold on DC means the breaker holds through starting surges up to roughly 535 A before instant tripping — critical for DC motor drives or capacitor bank charging. ## Deployment context Clip-on mounting to DIN rail (35 mm per EN 60715) with a width of 18 mm (2 x 9 mm pitches) means it occupies a single modular slot in a distribution board. The IP20 finger-safe enclosure and IP40 modular enclosure rating allow installation in standard electrical cabinets without additional shrouding. Tunnel-type terminals accept up to 35 mm² rigid stranded cable (AWG 2) or 25 mm² flexible, with a tightening torque of 3.5 N.m. The breaker is padlockable for lockout/tagout procedures and provides ON/OFF local signalling with a contact position indicator.","metaTitle":"Schneider Electric MGN61840 Multi9 C60H-DC MCB, 63 A, 1P, C","metaDescription":"Schneider Electric MGN61840 Multi9 C60H-DC miniature circuit-breaker. 63 A rated current, 1 pole, C curve, 20 kA breaking capacity at 110 V DC per EN/IEC 60947-2.
