The single-pole design and 18 mm width (1 modular unit) keep DIN-rail density high — that's another SKU that fits a standard 1-MW slot without crowding the next breaker. ## What the DC rating means for fit This is a DC-only breaker — the operating voltage is specified at 220 V DC with a maximum of 250 V DC. Unlike AC-rated MCBs that derate significantly on DC, this one is purpose-built for DC circuits. ## Panel integration and environment ## Compliance and approvals Rated per IEC 60947-2 for DC applications. Halogen-free and silicon-free construction. Sealable for lockout/tagout. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz.","metaTitle":"Siemens 5SY5110-7CC SENTRON MCB, 1P C 10 A DC, 10 kA","metaDescription":"Siemens SENTRON 5SY5110-7CC miniature circuit breaker, 1-pole, C-curve, 10 A DC, 10 kA breaking capacity per IEC 60947-2.
