Rated breaking capacity is 20 kA Icu at 110 V DC, 10 kA at 220 V DC, and 6 kA at 250 V DC, all conforming to EN/IEC 60947-2. The K-curve magnetic tripping limit is 12 x In +/- 20 % DC, which means it trips magnetically between roughly 9.6 and 14.4 times rated current — suited for loads with moderate inrush, like DC motor circuits or battery-backed supplies. It carries IP20 protection on the terminals and IP40 on the modular enclosure, so it's intended for enclosed panel mounting, not washdown environments. ## Terminal & Wiring Details Tunnel-type terminals accept a wide range of conductors: 1 to 35 mm² rigid stranded (AWG 18 to AWG 2) for a single cable, or up to 3 x 4 mm² flexible stranded. The breaker is padlockable and has a toggle control with ON/OFF indication and a contact position indicator.","metaTitle":"MGN61872 Multi9 C60H-DC MCB, 40 A, 1P, K Curve, DC","metaDescription":"MGN61872 Multi9 C60H-DC miniature circuit breaker, 40 A rated current, 1 pole, K curve, DC network, breaking capacity 20 kA at 110 V DC.
