It accepts solid conductors up to 35 mm², which covers most downstream feeder and branch-circuit wiring in a sub-distribution board. ## Ratings in Context Rated for multi-phase operation up to 440 V AC maximum, and for single-phase operation also at 440 V AC. The DC rating is 72 V maximum, which limits its use in DC circuits to low-voltage control or battery applications. Power loss is 1.6 W per pole under rated current at AC in hot operating state — relevant for thermal coordination within a multi-breaker enclosure.","metaTitle":"Siemens 5SN6316-7CP MCB, 3-Pole, C-Curve, 6 kA (EN 60898), 1","metaDescription":"Siemens 5SN6316-7CP 3-pole miniature circuit breaker, C-curve, rated 400 V AC, 6 kA per EN 60898, 15 kA per IEC 60947-2.

The key difference is breaking capacity: the 5SN6316-7CP is rated 6 kA per EN 60898 and 15 kA per IEC 60947-2, while the 5SL4363-7 is rated 10 kA per both standards. The 5SL also has a higher power loss per pole (5 W vs 1.6 W). For a panel originally specified around the 5SL4363-7, the 5SN6316-7CP will physically fit the same DIN-rail footprint and terminal wiring, but the lower breaking capacity must be verified against the fault-current study before substitution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SN6316-7CP","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/5SN6316-7CP when reusing this data.
