Dual-rated to IEC/EN 60898-2 and UL1077, so it passes both European and North American acceptance criteria for supplementary protectors. At 18 mm wide (1 MW), it fits standard 18 mm pitch terminal blocks and leaves room for adjacent breakers or auxiliaries. Sealable — useful for utility-metering or tamper-proof installations. IP20 with connected conductors, so it belongs inside an enclosure, not exposed to washdown.","metaTitle":"Siemens 5SY5105-7 SENTRON MCB, C-Curve 1P 10kA, 400V AC","metaDescription":"Siemens 5SY5105-7 SENTRON miniature circuit breaker, C-curve, 1-pole, 10kA per IEC/EN 60898-2, 400V AC.

Availability and current pricing are confirmed at quote time — no stock or price figures are published here."},{"question":"What is 5SY5105-7's listed depth (76 mm) on this component line?","answer":"The overall depth is 76 mm; the installation depth (behind the panel face) is 70 mm. At 18 mm wide (1 MW), it fits standard DIN-rail spacing."},{"question":"Will 5SY5105-7 drop into a panel that was specified around 5SY4140-7 without rewiring?","answer":"Yes — both are 1-pole SENTRON MCBs on the same 18 mm DIN-rail footprint with the same depth (76 mm). The 5SY5105-7 carries a C-curve and 10 kA breaking capacity; the 5SY4140-7 is a B-curve variant. If the panel was designed for a B-curve device, swapping to a C-curve changes the trip threshold (5–10× In vs 3–5× In) — verify coordination with downstream loads, but the mechanical fit is identical."},{"question":"What compliance documentation does this brand provide for 5SY5105-7 (RoHS, REACH, UL, IEC)?","answer":"The device is certified to IEC/EN 60898-2 and UL1077. The housing is halogen-free and silicon-free, which supports RoHS and REACH compliance. Standard Siemens SENTRON documentation (declaration of conformity, CE, UKCA) is available on request."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY5105-7","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/5SY5105-7 when reusing this data.
