Breaking capacity of 10 kA at 400 V AC under both EN 60898 and IEC 60947-2 means this breaker can safely interrupt a fault current up to 10,000 A without welding contacts or cascading failure upstream. That's the standard residential and light-commercial SCCR; if your transformer or service entrance can deliver more fault current, you need a higher-rated device or a current-limiting upstream breaker. The 3-pole design (3P) switches all three phases simultaneously, which is what you need for a three-phase final subcircuit. Sealable with a lead or tag, so a utility or facility manager can lock the setting against tampering. In a densely populated board, that heat adds up; factor it into your thermal calculation if the panel is near its fill limit.","metaTitle":"5SL4301-7 SENTRON MCB, 3P C 1A 400V 10kA","metaDescription":"Siemens SENTRON 5SL4301-7 miniature circuit breaker, 3-pole, C-curve, 1 A, 400 V AC, 10 kA breaking capacity per EN 60898/IEC 60947-2.

Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time."},{"question":"What is 5SL4301-7's listed depth (76 mm) on this component line?","answer":"The total depth is 76 mm, with an installation depth of 70 mm. That's the dimension from the DIN-rail mounting surface to the front face of the breaker."},{"question":"What is 5SL4301-7's listed width (54 mm) on this component line?","answer":"Width is 54 mm, which corresponds to 3 modular width units (each 18 mm) on a standard DIN rail. That's the space it occupies in a distribution board."},{"question":"Will 5SL4301-7 drop into a panel that was specified around 5SL4363-7 without rewiring?","answer":"The 5SL4301-7 and 5SL4363-7 share the same 3-pole, 3 MW form factor and DIN-rail mounting, so mechanical fit is identical. The difference is electrical: 5SL4301-7 is a 1 A C-curve, while 5SL4363-7 is a higher-rated variant. If the circuit design calls for 1 A protection, the 5SL4301-7 drops in without rewiring; if the original spec required a higher ampacity, you'd need to check the load."},{"question":"What compliance documentation does this brand provide for 5SL4301-7 (RoHS, REACH, UL, IEC)?","answer":"The 5SL4301-7 carries certifications to EN 60898 and IEC 60947-2 for breaking capacity. It is halogen-free and silicon-free, which aligns with RoHS material restrictions. For specific UL, REACH, or other regional compliance documentation, request the manufacturer's declaration at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL4301-7","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/5SL4301-7 when reusing this data.
