The 10 kA SCCR at 400 VAC tells you it can safely interrupt a fault up to that level without cascading upstream; the 15 kA rating at 220 VDC per IEC 60947-2 covers DC control circuits. Single-pole construction means it switches the line only — no neutral pole, so plan for a separate neutral bar in the panel. ## Panel integration and environment Rated IP20 with connected conductors — fine for a dry indoor enclosure, not for washdown zones. The operating range spans -40 °C to 75 °C, with derating above 55 °C per the humidity curve (95% RH up to 55 °C, 55% up to 70 °C, 35% at 75 °C). The breaker carries dual certification: IEC/EN 60898-2 for residential and commercial installations, and UL1077 for supplementary protection in North American panels. Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) covers the typical industrial panel mounted on a machine frame.","metaTitle":"Siemens 5SY5108-7 SENTRON MCB, C-Curve, 1P, 10 kA, 400 VAC","metaDescription":"Siemens 5SY5108-7 SENTRON miniature circuit breaker, 1-pole, C-curve, 10 kA breaking capacity per IEC/EN 60898-2 and UL1077.
