Its C-curve tripping characteristic means it holds through moderate inrush — typical for motor starters, contactor coils, and small transformers — before tripping at 5–10× rated current. The breaking capacity is rated 6 kA per EN 60898 and 10 kA per IEC 60947-2, with 15 kA at DC per IEC 60947-2 and 5 kA per UL 1077 / CSA C22.2 No. 235. That multi-standard coverage means it qualifies for IEC and UL installations without swapping parts. ## Integration and mounting Snaps onto DIN rail via the quick-assembly system, occupying one modular width unit (18 mm). Mounting position is any, which simplifies layout in crowded enclosures. Depth is 76 mm with an installation depth of 70 mm — enough clearance for standard gland plates. Combined top and bottom terminals accept supply from either side, and the neutral conductor is not switched, so it protects only the phase leg. IP20 with connected conductors means it is suited for enclosed panel use, not washdown zones. ## Environmental and compliance Rated for ambient temperatures from -40 °C to +75 °C, with humidity derating above 55 °C. Halogen-free and silicon-free construction — relevant for sensitive environments like semiconductor fabs or food processing where outgassing matters. Overvoltage category III and pollution degree 3 confirm suitability for fixed industrial installations.","metaTitle":"Siemens 5SY6163-7 SENTRON MCB, 1P C-Curve, 6kA/10kA, 18mm","metaDescription":"Siemens 5SY6163-7 SENTRON miniature circuit breaker, 1-pole, C-curve, 6 kA (EN 60898) / 10 kA (IEC 60947-2) breaking capacity.
