The breaking capacity is 6 kA per both EN 60898 and IEC 60947-2, so it can safely interrupt a fault up to 6 kA at 400 V AC without welding the contacts or cascading the fault upstream. The part carries no official successor because it is still active. If a buyer is cross-referencing from an older Siemens 5SL variant or a competitor's 4-pole C-curve 6A MCB, the key fit checks are the 3P+N wiring (not 4-pole independent), the 6 kA breaking capacity at 400 V AC, and the 4 MW DIN-rail footprint. The neutral-switching feature is present on this unit, so it is a direct drop-in for panels that require a switched neutral. ## Integration notes The 4 MW (72 mm) width means it occupies four adjacent 18 mm slots — plan the enclosure fill accordingly. Terminal screws accept up to 25 mm² conductors for the incoming and outgoing circuits.","metaTitle":"Siemens 5SL6606-7 SENTRON MCB, 4P C-Curve 6A 6kA 400V AC","metaDescription":"Siemens 5SL6606-7 SENTRON miniature circuit breaker, 4-pole (3P+N), C-curve, 6A, 6kA breaking capacity at 400V AC.

This means it can safely interrupt a short-circuit fault up to 6 kA without damage."},{"question":"Where can I buy 5SL6606-7 and how is it quoted?","answer":"This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time."},{"question":"What is the difference between 5SL6606-7 and 5SL4120-7CC?","answer":"The 5SL6606-7 is a 4-pole (3P+N) C-curve 6A MCB. The 5SL4120-7CC is a different variant in the same 5SL family — the key difference is the rated current and pole configuration. The 5SL6606-7 switches the neutral; the 5SL4120-7CC may not. Check the specific ratings before substituting."},{"question":"Does 5SL6606-7 switch the neutral?","answer":"Yes, the 5SL6606-7 is a 3P+N design with neutral conductor switching. The neutral pole opens and closes with the phase poles, which is required in some regional wiring codes and for TN-S systems."},{"question":"What compliance documentation is available for 5SL6606-7?","answer":"The 5SL6606-7 is a Siemens SENTRON product with standard CE marking for the European market. It is designed to meet EN 60898 and IEC 60947-2. Specific RoHS, REACH, and UL documentation should be requested at quote time from the supplier."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL6606-7","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/5SL6606-7 when reusing this data.
