The 0.3 A rating is temperature-sensitive: at 30 °C it holds 0.3 A, but at 55 °C it derates to 0.26 A. If this breaker lands in a warm enclosure — say, above a transformer or in a sunny meter cabinet — the effective continuous current drops. On the DC side, the maximum rated voltage is 72 V. That limits its use in DC sub-distribution unless the string voltage stays under that. For multi-phase AC operation, the maximum voltage is 440 V, so it fits standard 400 V three-phase networks with headroom. Sealable, halogen-free, and silicon-free — meets the material restrictions for clean-room-adjacent or food-beverage zones where silicone outgassing can contaminate product.","metaTitle":"Siemens 5SL4414-7 SENTRON MCB, 4P C-Curve 0.3A 10kA","metaDescription":"Siemens 5SL4414-7 SENTRON miniature circuit breaker, 4-pole, C-curve, 0.3 A rated, 10 kA breaking capacity per IEC/EN.

That is the same rating under both standards, so it coordinates cleanly in a residential or light-commercial distribution board without needing an upstream current-limiting fuse."},{"question":"What is the 5SL4414-7 used for?","answer":"It is a 4-pole miniature circuit breaker for residential buildings and infrastructure, protecting a 0.3 A AC circuit at 400 V with a C-curve characteristic. Typical use is final-subcircuit protection in a SENTRON distribution board."},{"question":"Where can I buy the 5SL4414-7?","answer":"Sourced and quoted to order against an RFQ through independent distribution channels.

The 5SL4414-7 is a 0.3 A C-curve; the 5SL4363-7 is a different rating. If the panel wiring and busbar are sized for the 5SL4363-7's rating, the 5SL4414-7 will physically fit without rewiring, but the ampacity must match the circuit design."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL4414-7","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/5SL4414-7 when reusing this data.
