Energy limitation class 3 keeps let-through energy low, protecting downstream wiring and loads. Rated current derates with ambient temperature: 59.16 A at 40 °C, 57.14 A at 45 °C, 55.06 A at 50 °C, 52.92 A at 55 °C, 50.65 A at 60 °C. Halogen-free and silicon-free construction; sealable with a lead or tag for lockout/tagout compliance. Supply cord position is any — no orientation restriction in the panel. The part is designed for mechanical engineering and general industrial use per the manufacturer's suitability listing. Compliance documentation (RoHS, REACH, CE) is available with the shipment.","metaTitle":"Siemens 5SY7163-7 SENTRON MCB, 1P C 63 A, 15/20 kA","metaDescription":"Siemens 5SY7163-7 SENTRON miniature circuit breaker, 1-pole C-curve 63 A, 15 kA (EN 60898) / 20 kA (IEC 60947-2), 50/60 Hz.
