The Siemens SENTRON 5SL6110-7MB is a 1-pole miniature circuit breaker rated 10 A with a C-curve trip characteristic, designed for 400 V AC residential and infrastructure branch circuits. Its 6 kA breaking capacity per EN 60898 covers most domestic and light commercial fault levels — enough for a sub-distribution board feeding lighting or socket outlets, but not for high-fault industrial panels where 10 kA or 25 kA ratings are common. The C-curve means it trips between 5× and 10× rated current, so it handles motor inrush from small pumps or fans without nuisance tripping while still clearing a hard short fast. Snaps onto standard DIN rail and occupies a single modular width unit (18 mm wide), so it fits a compact consumer unit or a crowded panel without eating up space. Rated for any mounting position, which simplifies layout in tight enclosures.
Panel fit and ratings
Depth of 76 mm and height of 90 mm — standard SENTRON compact footprint — so it drops into any existing DIN-rail panel that already holds a 5SL-series or 5SY-series MCB without rewiring or re-spacing. The IP20 rating (with connected conductors) is typical for enclosed distribution boards; no special sealing for washdown environments. Operating temperature range from -40 °C to 75 °C covers outdoor enclosures in cold climates and sun-exposed cabinets. Power loss is 1.2 W per pole at rated current in hot state — negligible for thermal budgeting in a multi-way board, but worth noting if the enclosure is sealed and densely packed. The breaker accepts supplementary devices (auxiliary contacts, shunt trips, alarm switches) for remote status or emergency-off integration.
