That's enough headroom for most industrial panel secondary-side protection — the 20 kA IEC figure is what you'd use for coordination studies under 60947-2. For motor or transformer primary-side protection, you'd typically step up to a C-curve. Fastening uses the quick assembly system, so it clips on and off without tools. ## Thermal derating and environmental range Rated 13 A at 35 °C ambient. Derates to 12.48 A at 40 °C, 12.22 A at 45 °C, 11.95 A at 50 °C, 11.67 A at 55 °C, and 11.39 A at 60 °C. If your panel internal ambient runs hot, factor that in — at 50 °C you lose about 1 A of headroom. Operating temperature range spans -40 °C to 75 °C, with humidity limits of 95% up to 55 °C, 55% up to 70 °C, and 35% at 75 °C. Designed for mechanical engineering and industry applications per its suitability listing. Sealable — allows lockout/tagout provisions on the toggle. Combined top and bottom terminals simplify busbar and outgoing wiring. Energy limitation class 3 indicates it limits let-through energy effectively during a fault, reducing stress on downstream components. Touch protection is built in. The product designation per IEC 81346-2 and DIN EN 61346-2 is 'F' (protective device). Current lifecycle stage — Siemens continues to manufacture this order code.","metaTitle":"Siemens 5SY4313-6 SENTRON MCB, 3P B-Curve 13 A, 10 kA","metaDescription":"Siemens 5SY4313-6 SENTRON miniature circuit breaker, 3-pole, B-curve, 13 A rated.
