The 10 kA breaking capacity per IEC 60947-2 tells you it safely interrupts a fault up to 10 kA at 440 V AC without upstream fuses needing to clear first — that's the SCCR number your panel label needs. C-curve means it trips between 5× and 10× In, so it handles motor inrush without nuisance trips but still clears fast on a hard short. ## Mounting and integration Snaps onto DIN rail via the quick-assembly system — one modular width unit (18 mm wide) so it takes a single slot in the panel. Depth is 76 mm, installation depth 70 mm, so it clears most standard enclosures. Mounting position any, which helps when you're packing breakers into a tight gland plate area. IP20 with connected conductors means it's touch-safe once wired but not for wet or dust-heavy environments. ## Environmental and compliance Halogen-free and silicon-free construction — relevant for clean-room or semiconductor fab panel specs where outgassing matters. Pollution degree 3 (conductive pollution or dry non-conductive that becomes conductive due to condensation) and overvoltage category III (equipment in fixed installations) match typical industrial control panel duty. Sealable terminals allow the panel builder to lock the breaker position after commissioning.","metaTitle":"Siemens 5SY4180-7CC SENTRON MCB, 80 A C-Curve 1P 10 kA","metaDescription":"Siemens 5SY4180-7CC SENTRON miniature circuit breaker, 80 A, C-curve, 1-pole, 10 kA per IEC 60947-2.
