It breaks 6 kA per EN 60898 and carries a 5 kA interrupting rating under UL 1077 / CSA C22.2 No. 235. This one sits on a DIN rail, takes one modular width unit (18 mm), and mounts in any position. It's sealable, halogen-free, and silicon-free, so it's fine for clean-room or food-line panels where outgassing matters. ## Temperature derating — the number that really matters The 4 A rating holds only up to 35 °C. At 40 °C it's 3.76 A; at 50 °C it's 3.5 A; at 55 °C it's 3.37 A. If your panel runs hot — and most industrial enclosures do — you need to size up one breaker or accept the reduced continuous current. This is the spec that trips up a BOM transfer from a 35 °C datasheet to a 50 °C panel.","metaTitle":"Siemens 5SY6104-8CC SENTRON MCB, D Curve, 4 A, 1P, 6 kA","metaDescription":"Siemens 5SY6104-8CC SENTRON miniature circuit breaker, D tripping characteristic, 4 A rated, 1 pole, 6 kA breaking capacity per EN 60898.

The part is sourced through independent distribution; availability and current pricing are confirmed at quote time."},{"question":"When sourcing 5SY6104-8CC, what's the closest functional alternative — 5SY4104-7CV?","answer":"The 5SY4104-7CV is a 1-pole, 4 A, 6 kA MCB but with a C curve instead of D. It shares the same 1 MWU footprint and 440 V AC rating. If your load is motor inrush or transformer magnetizing, stay with the D curve (5SY6104-8CC); for general-purpose or resistive loads the C curve (5SY4104-7CV) works and may be more available. They are not drop-in substitutes without verifying the trip characteristic against the load."},{"question":"What is 5SY6104-8CC's listed depth (76 mm) on this component line?","answer":"The overall depth is 76 mm; the installation depth behind the panel is 70 mm. That 6 mm difference accounts for the front bezel and toggle."},{"question":"What is 5SY6104-8CC's listed width (18 mm) on this component line?","answer":"Width is 18 mm, which is 1 modular width unit (MWU) on a standard DIN-rail panel. It occupies one slot in a multi-breaker row."},{"question":"Will 5SY6104-8CC drop into a panel that was specified around 5SY4104-7CV without rewiring?","answer":"Physically yes — same 1 MWU footprint, same DIN-rail clip, same 18 mm width, same 440 V AC rating. But the trip curve is different: D vs C. The wiring and busbar layout are identical; the only question is whether the load's inrush characteristic matches the D curve. If the original 5SY4104-7CV was marginal on startup, the D curve here gives more headroom."},{"question":"What compliance documentation does this brand provide for 5SY6104-8CC (RoHS, REACH, UL, IEC)?","answer":"The part carries a 6 kA breaking capacity per EN 60898 and a 5 kA interrupting rating per UL 1077 and CSA C22.2 No. 235. It is halogen-free and silicon-free, which supports RoHS and clean-room documentation requirements. The SENTRON series typically provides CE, UKCA, and EAC declarations; specific certificates should be requested with the RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SY6104-8CC","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/5SY6104-8CC when reusing this data.
