It is designed for DC distribution circuits and clips onto a DIN rail. Breaking capacity reaches 20 kA Icu at 220 V DC and 10 kA at 440 V DC per EN/IEC 60947-2, making it suitable for high-fault DC bus applications in industrial control panels. The 50 A continuous rating at 50 °C is the thermal limit for a single breaker in free air — if you group multiple units or mount in a higher ambient, you derate. Tunnel terminals accept up to 35 mm² rigid stranded or 25 mm² flexible — strip 14 mm, torque to 3.5 N.m. The enclosure is IP20 (IP40 in modular enclosure), so it needs a panel door or cover for washdown areas. Pollution degree 3 per EN 60947-2 means it tolerates conductive dust and occasional condensation — typical for industrial cabinets not in climate-controlled rooms.","metaTitle":"MGN61856 Multi9 C60H-DC MCB, 2P, 50 A, Curve C, DC","metaDescription":"MGN61856 Multi9 C60H-DC miniature circuit breaker, 2 poles, 50 A rated current, curve C, 20 kA breaking capacity at 220 V DC.
