The Siemens SENTRON 5SL6110-6YA is a 1-pole miniature circuit breaker (MCB) with a B tripping characteristic, rated at 10 A and a breaking capacity of 6 kA according to EN 60898.
For a 10 A circuit, that covers the vast majority of residential and light commercial service-entrance fault levels. The single-pole design switches only the phase; the neutral is not switched or protected. The 18 mm width (1 MWU) means it occupies one slot in a standard SENTRON distribution board, and the 76 mm depth plus 70 mm installation depth clears most enclosure gland plates without interference.
Panel integration and environmental limits
Mounting position is unrestricted — the breaker can be installed vertically, horizontally, or inverted on the DIN rail. The IP20 rating applies only with the distribution board cover fitted; the breaker itself is not sealed against dust or moisture ingress.
