It is designed for DC distribution networks and clips onto a DIN rail for panel integration. The breaking capacity reaches 20 kA Icu at 250 V DC, dropping to 10 kA at 440 V DC and 6 kA at 500 V DC, per EN/IEC 60947-2. This makes it suitable for protecting DC bus lines, battery banks, and DC motor circuits where high interrupting capability is required. ## DC Ratings and Breaking Capacity The rated operational voltage spans 220 V, 250 V, 440 V, and 500 V DC, with the rated insulation voltage at 500 V DC. The magnetic tripping limit is set at 8.5 x In ±20% DC, so a 63 A breaker trips instantaneously on a DC fault of roughly 536 A or more. The breaker occupies 4 x 9 mm pitches (36 mm width) on a DIN rail, with a depth of 73 mm and height of 81 mm. Clip-on mounting allows tool-less installation; the toggle handle provides local ON/OFF indication and a contact position indicator confirms the state. The tunnel-type terminals accept 1 to 35 mm² rigid stranded (AWG 18 to AWG 2) on top or bottom, with a tightening torque of 3.5 N.m.","metaTitle":"MGN61857 Multi9 C60H-DC MCB, 2P, 63 A, Curve C, DC","metaDescription":"MGN61857 Multi9 C60H-DC miniature circuit-breaker, 2-pole, 63 A rated current, C-curve, 20 kA breaking at 250 V DC.
