The curve-B magnetic trip triggers at 5.5 x In (±20 %) for DC circuits — meaning it clears short-circuit faults fast enough to protect downstream wiring and loads, but avoids nuisance trips on moderate inrush. Breaking capacity is 20 kA Icu at 110 V DC, 10 kA Icu at 220 V DC, and 6 kA Icu at 250 V DC — all per EN/IEC 60947-2. The toggle provides local ON/OFF indication, and the unit is padlockable for lockout/tagout procedures. ## Integration into a DC distribution panel Clip-on DIN rail mount, 18 mm width (2 modules). Tunnel-type terminals accept up to 35 mm² rigid stranded or 25 mm² flexible, with a stripping length of 14 mm and tightening torque of 3.5 N.m.","metaTitle":"MGN61809 Multi9 C60H-DC MCB, 1P, 40 A, Curve B, 20 kA DC","metaDescription":"MGN61809 Multi9 C60H-DC miniature circuit-breaker, 1P, 40 A, curve B, 20 kA Icu at 110 V DC.
