The Schneider Electric MGN61808 is a 1-pole DC miniature circuit breaker from the Multi9 C60H-DC series, rated 32 A at 50 °C with a B tripping curve. The thermal-magnetic trip unit protects DC circuits up to 250 V DC, with a magnetic trip threshold of 5.5 x In ±20% DC — meaning it clears short-circuit faults fast while riding through inrush on resistive or lightly inductive DC loads.
Breaking capacity and isolation
Rated Icu of 20 kA at 110 V DC, 10 kA at 220 V DC, and 6 kA at 250 V DC per EN/IEC 60947-2. That 20 kA figure at the common 110 V DC bus voltage means it handles high fault currents on telecom or solar combiner outputs without cascading upstream.
Strip length 14 mm, tightening torque 3.5 N.m.
