The B-curve trips between 3 and 5 times rated current (75–125 A), so it's sized for resistive and general-purpose loads — lighting circuits, small heaters, control transformers — where inrush isn't severe. At 72 mm wide (4 modular width units), it occupies four 18 mm DIN-rail slots. Snap-on DIN rail mounting, any orientation. ## Electrical performance and coordination Breaking capacity of 6 kA at 400 V AC per EN 60898 covers most residential and light commercial fault levels. Power loss per pole is 3.2 W at rated current in hot operating state — four poles total 12.8 W, which matters for thermal budgeting in a crowded enclosure. Vibration resistance tested to 50 m/s² at 25–150 Hz per IEC 60068-2-6, so it's fine on switchgear panels near rotating machinery.","metaTitle":"Siemens 5SL6425-6CC SENTRON MCB, 4P B 25A 400V 6kA","metaDescription":"Siemens 5SL6425-6CC SENTRON miniature circuit breaker, 4-pole, B-curve, 25A, 400V AC, 6kA breaking capacity per EN 60898.

The B-curve trips at 3–5x rated current, so it's not for motor circuits with high starting current."},{"question":"Where can I buy the 5SL6425-6CC?","answer":"We source and quote it to order against an RFQ. Send your target quantity and delivery timeline; we confirm availability and current pricing at quote time through independent distribution channels."},{"question":"How does the 5SL6425-6CC compare to the 5SL4363-7?","answer":"The 5SL4363-7 is a 3-pole C-curve 25A unit with 10 kA breaking capacity. The 5SL6425-6CC adds a fourth pole (switched neutral) and uses a B-curve instead of C-curve, so it's better suited for resistive loads where you need neutral switching. The 5SL4363-7 is 54 mm wide (3 MW), while the 5SL6425-6CC is 72 mm (4 MW) — it won't drop into a panel wired for the 3-pole without a wider DIN-rail slot and re-terminating the neutral."},{"question":"What compliance documentation does Siemens provide for this MCB?","answer":"The 5SL6425-6CC is designed to EN 60898 and IEC 60947-2 standards. It carries CE marking for the European market. RoHS and REACH compliance is standard for current SENTRON production. For specific declarations or UL/CSA documentation, request it with your RFQ — we can source the manufacturer's current compliance pack."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL6425-6CC","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/5SL6425-6CC when reusing this data.
