The Siemens SENTRON 5SL6110-6MB is a 1-pole miniature circuit breaker with B-curve tripping characteristic, rated 10 A at both 30 °C and AC, with a 6 kA breaking capacity per EN 60898. It handles single-phase circuits up to 250 V AC and multi-phase up to 440 V AC (400 V rated supply). The DC rating tops out at 72 V. This is a current-production part — no end-of-life notification on file.
Snaps onto DIN rail; 18 mm width means it occupies exactly one modular-width unit (1 MWU). Mounting position is unrestricted — horizontal, vertical, or flat.
The closest functional peer in the same SENTRON 5SL family is the 5SL6132-6MB — identical physical footprint, B-curve, 6 kA rating, and 1-pole form factor. The only difference is the current rating: 32 A vs. 10 A. If a panel was specified around the 32 A version and you need a 10 A branch, the 5SL6110-6MB drops into the same DIN slot without rewiring the busbar or enclosure layout.
Lifecycle status is active — no phase-out, no last-time-buy window. The part carries Siemens SENTRON branding and is compliant for residential/infrastructure duty.
