Under UL 1077 the AC rating is 5 kA — the UL figure governs installations that follow the US code; the IEC figure governs the rest of the world. The DC rating matters for 24 V control circuits or 48 V telecom supplies where a fault can sustain an arc longer than AC. The 18 mm width (1 MW) snaps onto standard DIN rail. Mounting position is unrestricted, and the quick-assembly system means it clips into a multi-pole ganged assembly without tools. Depth behind the panel is 70 mm; overall depth is 76 mm — verify gland-plate clearance if the enclosure is shallow. The breaker is certified to IEC / EN 60947-2 and UL 1077. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz — within the range of typical motor-starter panels mounted on a machine frame.","metaTitle":"Siemens 5SY8101-7 SENTRON MCB, 1P C-curve, 70 kA IEC","metaDescription":"Siemens 5SY8101-7 SENTRON miniature circuit breaker, 1-pole C-curve, 70 kA breaking capacity per IEC 60947-2, 15 kA DC.
