Siemens SENTRON 5SL3310-7 miniature circuit breaker, 3-pole, C-curve, 10 A, 400 V AC, 4.5 kA breaking capacity per EN 60898, 3 modular width units (54 mm).

It's designed for overcurrent and short-circuit protection in residential and infrastructure AC circuits up to 400/440 V. Breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 — enough for most residential and light commercial panelboards where the prospective fault current stays under that threshold.
Rated 10 A at 30 °C ambient; derates to 9.52 A at 40 °C and 8.74 A at 55 °C. Sealable, halogen-free, silicon-free.
Both are 3-module-width (54 mm) SENTRON MCBs on the same DIN-rail footprint, so the 5SL3310-7 drops into the same panel position without rewiring. The difference is the rating — 10 A C-curve here versus the higher ampacity of the 5SL4363-7.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
