The 20 kA breaking capacity at 250 V DC means it can safely interrupt high-fault DC arcs — a different failure mode than AC, which is why this part carries its own EN/IEC 60947-2 listing. ## Breaking capacity and voltage ratings Breaking capacity varies with system voltage: 20 kA Icu at 220 V DC and 250 V DC, 10 kA at 440 V DC, and 6 kA at 500 V DC. Rated operational voltage options are 220 V DC, 250 V DC, 440 V DC, and 500 V DC. For a 250 V DC bus — common in telecom or solar combiner boxes — the full 20 kA is available. At 500 V DC the breaker still holds 6 kA, which covers most battery-bank or UPS distribution applications. ## Thermal-magnetic trip and isolation suitability The thermal-magnetic trip unit handles overloads (thermal) and short-circuits (magnetic). ## Durability and environmental ratings Mechanical durability is rated at 20,000 cycles; electrical durability at 3,000 cycles with L/R = 2 ms (a standard DC time constant). IP20 at the terminals, IP40 on the modular enclosure. Tropicalisation class 2 per IEC 60068-2 means it's treated against humidity and mould — relevant for warm, non-air-conditioned enclosures. Relative humidity tolerance is 95% at 55 °C. Dual and triple cable entries are supported: two cables up to 16 mm² each, or three 4 mm² cables. Strip length 14 mm. The breaker is padlockable for lockout/tagout.","metaTitle":"Schneider MGN61823 Multi9 C60H-DC MCB, 63 A, 2P, Curve B, DC","metaDescription":"Schneider Electric MGN61823 Multi9 C60H-DC miniature circuit breaker, 63 A, 2-pole, curve B, 20 kA breaking capacity at 250 V DC.
