The IP20 rating applies with conductors connected — fine inside a closed enclosure, not for wet locations. Mounting position is unrestricted, so it can go sideways or upside-down in a tight gland plate layout without derating.","metaTitle":"Siemens 5SL6308-7BB SENTRON MCB, 3P C 8A 6kA","metaDescription":"Siemens SENTRON 5SL6308-7BB miniature circuit breaker, 3-pole, C-curve, 8A, 400V AC, 6kA breaking capacity per EN 60898.

The 5SL4363-7 carries a 10 kA breaking capacity versus 6 kA on this part, but the physical footprint is identical, so no rewiring or panel modification is needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SL6308-7BB","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/5SL6308-7BB when reusing this data.
