The Siemens 5SY4316-8CV is a 3-pole miniature circuit breaker (MCB) with a D tripping characteristic, rated 16 A at 35 °C and delivering a 15 kA breaking capacity per IEC 60947-2.
Rated current drops with ambient temperature: 14.83 A at 40 °C, 14.21 A at 45 °C, 13.6 A at 50 °C, 12.86 A at 55 °C. That's a straight derating curve — if your panel hits 50 °C internal, you're effectively running a 13.6 A breaker.
15 kA per IEC 60947-2 at 400 V AC, 50/60 Hz.
The D tripping characteristic (10–20× In) handles high inrush loads like motors, transformers, and welding equipment without nuisance tripping on startup.
