The B curve trips between 3–5× rated current — fast enough for resistive loads and short cable runs, but won't ride through motor inrush like a C or D curve would. If you're feeding a motor starter directly, step up to a C-curve sibling; the B characteristic is better suited to the panel's outgoing lighting and control circuits. Temperature derating is published: at 35 °C it holds full 25 A; at 40 °C it's 23.5 A; at 50 °C it drops to 21.9 A. Mounts in any position. Halogen-free and silicon-free construction. Sealable for lockout/tagout. IP20 with connected conductors. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Ambient humidity limits: 95% up to 55 °C, 55% up to 70 °C, 35% up to 75 °C.","metaTitle":"Siemens 5SY6325-6CC SENTRON MCB, 25A 3P B-Curve, 6kA","metaDescription":"Siemens SENTRON 5SY6325-6CC miniature circuit breaker, 25A, 3-pole, B characteristic, 6kA per IEC 60898.
