Under UL 1077 and CSA C22.2 No. 235 it holds a 5 kA interrupting rating — that's the number to use for North American supplementary protection listings. Any mounting position is allowed. Combined terminals top and bottom simplify busbar and outgoing wiring. Neutral conductor switching is integrated — no separate neutral link needed. Derate the 50 A rating at elevated temperatures: 48.95 A at 50 °C, 47.85 A at 55 °C. Halogen-free and silicon-free construction. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Suitability marked for mechanical engineering and industry. ## Lockout & Touch Protection The breaker is sealable — padlockable in the OFF position for positive isolation during maintenance. Touch protection is built in per the product feature. If it's not locked, it's not safe — this one accepts a lock.","metaTitle":"Siemens 5SY8650-7 SENTRON MCB, 50A C-Curve 4P 25kA","metaDescription":"Siemens 5SY8650-7 SENTRON miniature circuit breaker, 50 A rated, C characteristic, 4-pole (3P+N), 25 kA breaking capacity at 400 V AC per IEC 60947-2.
