The 250 VDC rated voltage and 10 kA breaking capacity define its application envelope: it protects a single DC bus or load branch, not an AC circuit. At 100 A, this is a high-current single-pole DC breaker; most SENTRON 5SL series MCBs top out at 20 A or 16 A on AC. The 1.5 modular width units (27 mm wide) mean it occupies one-and-a-half standard 18 mm DIN-rail positions, so check your panel layout — it will not fit a single-width slot. The 70 mm depth and 90 mm height match the SENTRON 5SL and 5SP family footprint, so it aligns with adjacent breakers in a multi-pole arrangement. IP20 with connected conductors — suitable for enclosed panel installation, not for wet or washdown environments. Tunnel terminals top and bottom accept copper conductors; halogen-free and silicon-free construction avoids outgassing concerns in sealed enclosures. ## Supplementary devices and mechanical endurance Shock resistance tested to 150 m/s² at 11 ms half-sine, vibration resistance to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 s) — robust enough for industrial machinery and transport applications.","metaTitle":"Siemens 5SP5191-7CC SENTRON MCB, 1P, C-curve, 100 A, 250 VDC","metaDescription":"Siemens SENTRON 5SP5191-7CC miniature circuit breaker, 1-pole, C-curve, 100 A, 250 VDC, 10 kA breaking capacity.

It carries IP20 protection with connected conductors, and is rated to IEC 60947-2 for DC breaking capacity. The SENTRON series typically includes CE, UL, and CSA certifications, though specific listing marks for this exact variant should be verified on the nameplate or via the manufacturer's declaration of conformity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SP5191-7CC","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SP5191-7CC when reusing this data.
