That 880 V DC rating makes it a fit for series-connected solar strings or DC bus sections where you need overcurrent protection at elevated DC voltages — not a standard 24 V or 48 V auxiliary breaker. The quick-assembly fastening system and any-position mounting simplify panel layout — no orientation restrictions. IP20 with connected conductors is the protection class, so it belongs inside an enclosure, not exposed. Halogen-free and silicon-free construction suits clean-room or sensitive electronics environments. Vibration resistance tested to IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz).","metaTitle":"Siemens 5SY5401-7CC SENTRON MCB, 880V DC, 10kA, 4P, C, 1A","metaDescription":"Siemens SENTRON 5SY5401-7CC miniature circuit breaker, 880V DC, 10kA (IEC 60947-2), 4-pole, C-curve, 1A.
