The Siemens SENTRON 5SL6210-7BB is a 2-pole miniature circuit breaker with a C tripping characteristic, rated 10 A at 30 °C and 400 V AC.
At 10 A it protects 2.5 mm² copper wiring in a 230/400 V distribution board. Temperature derating is published: 9.24 A at 40 °C, 8.8 A at 45 °C, 7.96 A at 55 °C.
Mounting position is unrestricted, which simplifies layout in tight cabinets.

The 5SL6550-7BB is a higher-rated variant in the same SENTRON 5SL6 family. The 5SL6210-7BB is a 10 A C-curve 2-pole breaker; the 5SL6550-7BB carries a higher current rating. Both share the same 2-pole, C-curve, 6 kA breaking capacity, and 36 mm width footprint, so the 5SL6550-7BB will physically drop into the same DIN-rail position without rewiring, but the ampacity difference must match the circuit design.
The breaker is certified to EN 60898 and IEC 60947-2 for breaking capacity. It carries an IP20 protection class (with connected conductors), is halogen-free and silicon-free, and is designed for overvoltage category III, pollution degree 2. The manufacturer provides standard declarations of conformity; specific RoHS/REACH/UL documentation can be requested at quote time.
