Derates to 0.95 A at 40 °C, 0.93 A at 45 °C, 0.9 A at 50 °C, 0.88 A at 55 °C, and 0.85 A at 60 °C. If the panel ambient runs above 35 °C, size up accordingly — a 40 °C panel means this breaker handles 0.95 A continuous, not 1 A. ## Environmental and Compliance — Halogen-Free, Silicon-Free, Sealable Halogen-free and silicon-free construction. Sealable per the spec — allows lockout/tagout on the toggle. IP20 with connected conductors (finger-safe when wired). Energy limitation class 3. Functional identification per IEC 81346-2 and DIN EN 61346-2 as letter F (protective device).","metaTitle":"Siemens 5SY5201-7KK11 SENTRON MCB, 1A C-Curve 2-Pole, 10kA","metaDescription":"Siemens 5SY5201-7KK11 SENTRON miniature circuit breaker, 1A rated, C tripping characteristic, 2-pole, 10 kA breaking capacity per EN 60898.
