Product details

Breaking capacity and standards

DIN-rail footprint and derating

Mounting position is any, so you can lay it horizontally or vertically inside a shallow enclosure. Rated 10 A at 30 °C ambient. At 40 °C derate to 9.3 A; at 45 °C to 9 A. If your panel runs warm — near a transformer or in a sealed enclosure — use the derated figure for the continuous load.

Construction and environmental

Halogen-free and silicon-free construction, sealable with a lead or tag, and touch-protected terminals. IP20 with connected conductors — fine inside a cabinet, not for wet locations. Mechanical life is 20 000 switching cycles typical.

Frequently asked questions

What is the breaking capacity of 5SL6510-7MB?

6 kA per both EN 60898 and IEC 60947-2 at 230 V AC.

Where can I buy the 5SL6510-7MB and get current pricing?

Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

What is the difference between 5SL6510-7MB and 5SL6550-7BB?

The 5SL6550-7BB is a B-curve breaker (magnetic trip 3–5× In) versus the C-curve on this 5SL6510-7MB. Both are 1P+N, 10 A, 6 kA SENTRON MCBs. The B curve suits resistive loads and short cable runs; the C curve handles moderate inrush from motors and transformers. They are dimensionally identical and drop into the same panel without rewiring.
