Product details

The Siemens 5SL6310-7MB is a SENTRON miniature circuit breaker (MCB) — 3-pole, C-curve, rated 10 A, with a 6 kA breaking capacity per EN 60898 at 400 V AC.

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.

Frequently asked questions

What is the closest functional alternative to 5SL6310-7MB?

The 5SL4363-7 is the closest sibling — same 3-pole C-curve form factor, but rated 10 kA per EN 60898 and IEC 60947-2 instead of 6 kA. It drops into the same DIN-rail footprint and accepts the same auxiliary devices.
