Rated operational voltage is 400 V AC for multi-phase (3P) use, with a maximum of 440 V AC. Single-phase operation is rated at 250 V AC. The DC side is limited to 72 V maximum — not a DC-rated breaker for solar or battery strings. Power loss per pole is 1.2 W in hot operating state at rated current — useful for thermal derating calculations when packing multiple breakers in an enclosure. ## Integration notes IP20 with connected conductors; suitable for clean, dry indoor panels. Sealable (can be locked in OFF position) for lockout/tagout. Halogen-free and silicon-free construction. Supplementary devices (shunt trip, auxiliary contacts, alarm switch) can be snapped onto the right side.","metaTitle":"Siemens 5SL6310-7MB SENTRON MCB, 3P C 10A 6kA 400V","metaDescription":"Siemens 5SL6310-7MB SENTRON miniature circuit breaker, 3-pole, C-curve, 10 A, 6 kA per EN 60898 at 400 V AC.
