It carries a breaking capacity of 20 kA Icu at 110 V DC, 10 kA Icu at 220 V DC, and 6 kA Icu at 250 V DC, all certified to EN/IEC 60947-2. ## DC-rated protection with C-curve selectivity The C-curve (magnetic tripping limit 8.5 x In ±20 % DC) means this breaker clears short-circuits between roughly 27 A and 41 A for a 4 A rating — suited for loads with moderate inrush, like DC power supplies or control transformers, where a B-curve would nuisance-trip but a D-curve might let a fault ride through too long. Thermal-magnetic trip technology combines a bimetal element for overload protection (time-delayed) with a solenoid for instantaneous short-circuit interruption, both calibrated for DC applications where the lack of a zero-crossing makes arc extinction more demanding than on AC. Depth of 73 mm and height of 81 mm fit within standard enclosure depths — verify clearance for the toggle actuator and tunnel-type terminals. Tunnel-type terminals accept up to 25 mm² rigid stranded (AWG 4) or 16 mm² flexible, with a stripping length of 14 mm and tightening torque of 2.5 N·m. The IP20 finger-safe front (IP40 in modular enclosure) meets the usual panel-side requirement. Certified to EN/IEC 60947-2, utilisation category A (non-selectivity-oriented). Tropicalisation class 2 per IEC 60068-2 covers damp-heat exposure. Rated insulation voltage 500 V DC; operational voltage ratings at 110 V, 220 V, and 250 V DC. Suitability for isolation confirmed per the same standard — the contact position indicator and padlockable toggle provide visible isolation for safe maintenance.","metaTitle":"MGN61827 Multi9 C60H-DC MCB, 1P, 4 A, C-Curve DC","metaDescription":"MGN61827 Multi9 C60H-DC miniature circuit breaker, 1-pole, 4 A, C-curve, 20 kA at 110 V DC per EN/IEC 60947-2.
