At 10 A it handles a 2.3 kW resistive load on 230 V single-phase. The 10 kA (EN 60898) / 20 kA (IEC 60947-2) SCCR means it can safely interrupt a fault up to that level without welding contacts or cascading upstream; the higher IEC 60947-2 figure is the one to use for industrial panel coordination studies. The thermal derating is published: 9.39 A at 40 °C, 8.74 A at 50 °C, 8.04 A at 60 °C (cites:,). If your enclosure runs warm, size the upstream protection for the derated value, not the 10 A nameplate. Pollution degree 3 and overvoltage category III confirm it's rated for fixed installations inside industrial enclosures where conductive dust or condensation is possible (cites:,). ## Mounting and integration Snaps onto DIN rail via the quick-assembly fastening system; 18 mm width equals 1 modular unit, so it occupies one slot in a standard distribution board (cites:,). Installation depth is 70 mm, overall depth 76 mm — check your enclosure depth if you're using a shallow gland plate (cites:,). Mounting position is any, which helps in tight retrofit panels (cites:). Combined terminal top and bottom — line and load can land on either side, no polarity concerns. Sealable, so you can lock the toggle position with a padlock for lockout/tagout (cites:,). IP20 with connected conductors — fine inside a closed panel, not for wet or outdoor locations (cites:).","metaTitle":"Siemens 5SY4110-6KK11 SENTRON MCB, 1P B-Curve 10A, 10/20kA","metaDescription":"Siemens 5SY4110-6KK11 SENTRON miniature circuit breaker, 1-pole, B-curve, 10A rated, 10kA (EN 60898) / 20kA (IEC 60947-2) breaking capacity.
