It occupies one modular width unit (18 mm) on the DIN rail, with a depth of 76 mm and a height of 90 mm. The quick-assembly fastening system and combined top/bottom terminals simplify busbar and wiring connections. With an IP20 rating (with connected conductors) and pollution degree 3, it is suitable for installation in industrial control panels where dust and non-conductive contamination are present. Rated for ambient temperatures from -40 °C to 75 °C, with humidity derating above 55 °C. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, so it holds up on machine-mounted panels.","metaTitle":"Siemens 5SY7104-8CC SENTRON MCB, D Curve, 1-Pole, 30 kA","metaDescription":"Siemens 5SY7104-8CC SENTRON miniature circuit breaker, D tripping characteristic, 1-pole, 30 kA per IEC 60947-2.

The D curve's higher magnetic trip threshold makes the 5SY7104-8CC the correct choice for loads with high inrush — the 5SY4101-7CV would nuisance-trip on the same motor or transformer start-up. Panel footprint (18 mm width, DIN rail) is shared, so mechanical fit is the same, but the trip curve difference means they are not drop-in functional substitutes."},{"question":"What compliance documentation does Siemens provide for 5SY7104-8CC?","answer":"The breaker is rated per IEC 60947-2 (30 kA breaking capacity) and UL 1077 / CSA C22.2 No. 235 (5 kA). It carries pollution degree 3 and overvoltage category III ratings.
