The 70 mm depth (including terminals) and 110 mm height are standard for this class, so it clears most enclosure backplates and leaves room for wiring ducts. Ambient temperature range of -40 to 75 °C covers unheated warehouses and hot cabinet interiors alike; the 95 % humidity rating means condensation-prone environments are fine as long as the IP20 body (IP40 at the handle) is kept dry. The vibration resistance (50 m/s² at 25–150 Hz, 60 m/s² at 35 Hz for 4 s) means it holds up on machine-mounted subpanels near conveyors or compressors. ## Integration notes The sealable design (padlockable toggle) allows lockout/tagout without an external hasp. Halogen-free and silicon-free construction avoids corrosive off-gassing in sealed enclosures. Neutral conductor is not switched — this is a single-pole line-side breaker only.","metaTitle":"Siemens 5SJ4102-8HG41 SENTRON MCB, 1P, D-curve, 10 kA","metaDescription":"Siemens 5SJ4102-8HG41 SENTRON miniature circuit breaker, 1-pole, D tripping characteristic, 10 kA (EN 60898) / 15 kA (IEC 60947-2).

The higher IEC figure applies when the breaker is used in industrial distribution per 60947-2."},{"question":"What does the D tripping characteristic mean?","answer":"The D curve trips at 10–20 times rated current, designed for loads with high inrush like motors, transformers, or welding equipment. It avoids nuisance tripping on startup that a B or C curve would cause."},{"question":"Where can I buy 5SJ4102-8HG41 and how is it quoted?","answer":"Sourced and quoted to order against an RFQ through independent distribution.

The 5SJ4102-8HG41 uses combined terminals (top and bottom) rather than tunnel terminals, so wiring method differs slightly, but the physical footprint and rail clip are interchangeable."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SJ4102-8HG41","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/5SJ4102-8HG41 when reusing this data.
